     19Every [/roadmap month] the team of JOSM [wikitr:/Releases releases] a **tested version** for download.
     20The MS Windows and Apple macOS variants are built on this tested version.
     21When you click on josm.jnlp to launch JOSM you will always get the newest tested version. Java's [wikitr:/InstallNotes#Webstart Web Start] is the mechanism behind this.
     22
     23[=#DevelopmentVersion]
     24Every [/log/josm/?verbose=on&limit=20 night] the build systems generate a **latest version**.
     25These versions might have severe errors. But mostly they work well, too.
     26For the latest version is also a Web Start variant available.

     56** Strip translations **[=#Striptranslations]  \\
     57If download size is an issue, smaller files of the tested version are available. For downloads containing only English append [/josm-tested.jar?lang=en ?lang=en] to the URL. To include one translation replace `en` with the [wikitr:/TracLanguages language code] you want (lowercase first character, supported languages only). You can further reduce the file size by stripping the signing information off with appending [/josm-tested.jar?lang=en&unsigned=1 ?unsigned=1].

     60== Linux Repositories ==
     61=== JOSM's Debian based mainly for Ubuntu ===#Ubuntu
     62This is our own package repository primarily for Ubuntu. It should also work with other Debian based (especially Ubuntu based) distributions, but we do not actively test and maintain any distributions other than Ubuntu.
     63
     64The repository contains two packages:
     65* ''josm'' – Provides the tested version (stable). Replaces the package from the official repository of your distribution. The default JOSM directories name is set to `JOSM`.
     66* ''josm-latest'' – The latest version (nightly). Can be installed in parallel to the josm package, therefore the default JOSM directories name is set to `JOSM-latest`.
     67Both packages provide `/etc/default/josm` respectively `/etc/default/josm-latest` as config file for [wikitr:Help/CommandLineOptions#Javaoptions java options].
     68
     69In addition to the regular procedure described below, older DEBs can be manually downloaded from the [/apt/pool/universe/j/ archives].
     70
     71==== Installation ====
     72Edit the package resource list `/etc/apt/sources.list.d/josm.list`:
     73{{{#!sh
     74sudo editor /etc/apt/sources.list.d/josm.list
     75}}}
     76{{{#!comment
     77### below does not work on GNU Debian systems
     78`sudo $EDITOR /etc/apt/sources.list.d/josm.list`
     79}}}
     80
     81and add one of the following lines according to your Ubuntu-Version:
     82
     83{{{#!sh
     84deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt plucky universe
     85deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt oracular universe
     86deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt noble universe
     87deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt jammy universe
     88deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt focal universe
     89deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt bionic universe
     90
     91# For other Debian based distributions add:
     92deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt alldist universe
     93}}}
     94
     95Alternatively, this can be done with the following one-liner in Ubuntu (not for Ubuntu based distributions like Linux Mint):
     96{{{#!sh
     97echo "deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt $(lsb_release -sc) universe" | sudo tee /etc/apt/sources.list.d/josm.list > /dev/null
     98}}}
     99or for Linux Mint:
     100{{{#!sh
     101echo "deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt $(grep ^DISTRIB_CODENAME= /etc/upstream-release/lsb-release| awk -F = '{print $(2)}') universe" | sudo tee /etc/apt/sources.list.d/josm.list > /dev/null
     102}}}
     103
     104{{{#!comment
     105### below did not work on all systems
     106and add the following line:
     107{{{#!sh
     108`deb [signed-by=/etc/apt/keyrings/josm-apt.gpg] https://josm.openstreetmap.de/apt VERSION universe`
     109}}}
     110}}}
     111
     112Download the [/josm-apt.key public key]:
     113{{{#!sh
     114sudo curl https://josm.openstreetmap.de/josm-apt.key -o /etc/apt/keyrings/josm-apt.gpg
     115}}}
     116
     117In the past, instructions used `apt-key`. If the key was added to system's keyring, following line will remove it. This is never required, except it stops JOSM from signing packages that are NOT josm.
     118{{{#!sh
     119sudo apt-key del $(apt-key list | grep -B1  "<josm-dev@openstreetmap.org>" | sed '$d' | cut -b 48-51,53-57)
     120}}}
     121
     122Now refresh your sources:
     123{{{#!sh
     124# You may need to install ssl support for apt in advance:
     125sudo apt-get install apt-transport-https
     126# Refresh sources
     127sudo apt-get update
     128}}}
     129
     130and install:
     131{{{#!sh
     132# You can skip this first line if these packages were not installed before.
     133sudo apt-get remove josm josm-plugins
     134
     135# For the tested version
     136sudo apt-get install josm
     137# For the development version
     138sudo apt-get install josm-latest
     139}}}
     140
     141
     142=== GNU Debian ===#GNUDebian
     143Our own Ubuntu packages, [#Ubuntu above], work on Debian and we recommend to use them. Depending on the setup of `sudo`, some instruction will not work as "normal" user but only as `root`.
     144
     145The tested version of [https://packages.debian.org/stable/josm JOSM] is available under **''main''** in section **''utils''**, but the version is usually quite old. \\
     146Please, use the [https://backports.debian.org backports repository] to get a more up-to-date version, see [https://backports.debian.org/Instructions Instructions]. This version might still be older than our own packages.
     147
     148Since Debian 11 (bullseye) the [https://packages.debian.org/stable/josm-installer josm-installer] is available under **''main''** in section **''utils''**. It downloads the current .jar file from this site and updates it if necessary.
     149
     150=== openSUSE  ===#Opensuse
     151The tested version of JOSM is available in the Application:Geo repository.[=#openSUSE]
     152
     153First add as root user in yast or with zypper the repository (for Tumbleweed replace **$releasever** with **openSUSE_Tumbleweed**):
     154{{{#!sh
     155zypper ar -f 'https://download.opensuse.org/repositories/Application:/Geo/$releasever' Application:Geo
     156}}}
     157
     158Then simply install ''josm'' and ''josm-fonts'' package.
     159
     160=== Arch Linux ===#ArchLinux
     161
     162The official repository contains the `josm` [https://archlinux.org/packages/extra/any/josm/ package], which can be installed via `pacman -S josm`.
     163
     164The Arch user repository (AUR) additionally contains the `josm-latest` [https://aur.archlinux.org/packages/josm-latest package] with the latest version of JOSM.
     165Use your AUR helper to install this package.
     166
     167Both packages are third-party-packages and not maintained by the JOSM-team.

    42169== Troubleshooting ==
    43 === Troubleshooting jar file ===
    44 
    45 ==== Double click on a file does nothing ====
    46 
    47 In most cases this means Java (JVM) wasn't installed. JOSM is tested and developed with Oracle JVM, therefore it is recommended to get it from java.com site.
    48 
    49 * https://www.java.com/en/download/ - main resource, usually Installation process goes without any problems
    50 * https://www.java.com/en/download/help/download_options.xml - additional steps for all systems
    51 * https://www.java.com/en/download/help/index_installing.xml?os=All+Platforms&j=8&n=20 - please narrow down your question at their help portal about questions during installation
    52 
    53 If at least one Java was installed, refer to pages:
    54 * https://www.java.com/en/download/help/troubleshoot_java.xml - it contains most common troubleshooting questions
    55 * https://www.java.com/en/download/help/ - this page contains "Top 8 Java Issues", one of them may be yours
    56 
    57 ==== Strip down unnecessary translations in .jar ====
    58 
    59 If download size is an issue for you:
    60  * Append **?lang=…** to the download link address for both releases to strip unused translations (e.g. **?lang=de** will download JOSM in German language only).
    61  * **Note**: Use underscore to separate [[Translations|language codes]] with country code extensions, e.g. **?lang=en_GB**
    62  * Append **?unsigned=1** to strip the code signing information
    63  * When **lang** and **unsigned** are used the separation is a **&** sign like in **?lang=de&unsigned=1**
    64 
    65 10786 .jar: 10.2M[[br]]

    69 === Troubleshooting jhlp link ===
    70 
    71 Assuming, [wiki:Download#Doubleclickonafiledoesnothing JVM was already installed], read [https://www.java.com/en/download/faq/java_webstart.xml Web Start] help.
    72 
    73 === Troubleshooting JVM ===
    74 
     170=== Java ===#Java
     171When you double-click on a jar file and nothing happens in most cases this means Java isn't installed.
     172
     173JOSM now recommends [https://www.azul.com/downloads/?version=java-21-lts&package=jdk-fx#zulu Azul] or [https://bell-sw.com/pages/downloads/?package=jre-full#mn Bellsoft Liberica] JDK's. Generally speaking, the current Java LTS should be preferred (at time of writing, that would be Java 17), but Java 11 will work. See the [source:/trunk/README README] for current recommendations. But first give the Java already distributed with the operating system a try, [https://en.wikipedia.org/wiki/OpenJDK for example].
     174
     175
     176When choosing a download keep in mind:
     177 * A Java Plug-in for web browsers is **not** needed to run JOSM. Therefore results from pages like www.java.com/en/download/installed8.jsp are not relevant.
     178 * A Java variant with 64 bit is recommended for JOSM. The operating systems architecture is important for deciding between 32 bit Java or 64 bit Java. Because JOSM is **not** affected by the web browsers architecture most recommendations on this page www.java.com/en/download/faq/java_win64bit.xml are not relevant.
     179 * Avoid pages like www.java.com/en/download which intent to place Java Plug-ins in web browsers. And this is **not** important for JOSM.
     180
     181For further information visit the [wikitr:/InstallNotes Installation Notes] and [https://www.java.com/en/download/help/troubleshoot_java.xml troubleshooting] pages.
     182''Java'' in this section means a JRE (Java Runtime Engine) which provides a JVM (Java Virtual Machine) to run JOSM, a Java program that is developed using JDK (Java Development Kit) and sometimes launched with the JNLP (Java Network Launch Protocol aka Web Start and successor of Java Plug-ins).
     183
     184==== Testing Java ====#JavaTest
     185[=#Troubleshootingjarfile] Checks if Java is installed and why JOSM does not start (example mainly for MS Windows).
     1861. Download [/josm-tested.jar josm-tested.jar] to your desktop.
     1871. Open a Command Prompt aka Terminal
     1881. Type `cd %homepath%`⏎ and type `cd Desktop`⏎
     1891. Type `java -version `⏎ Three lines with the version data should appear. If you see something else then Java is not properly installed.
     1901. Type `java -jar josm-tested.jar`⏎. Now JOSM should run, started from the [wikitr:/Help/CommandLineOptions Command Line].
     1911. Quit JOSM.
     1921. Type `josm-tested.jar`⏎. If JOSM starts again, the Windows Explorer is ready for double clicks on jar files.
     193
     194
     195=== Web Start ===#Webstart
     196[=#Troubleshootingjhlplink]
     197You need to install [https://openwebstart.com/ OpenWebStart] first. It will download and run Java by itself. Please use the 64 bit (`x64`) version of OpenWebStart if you are on Microsoft Windows. The transition from Oracle WebStart to OpenWebStart is still in progress, so in case of issue please create a [/newticket new ticket] or post a comment to #17858.
     198
     199You may need to update the default application for opening JNLP files if you previously used Oracle WebStart. See [https://openwebstart.com/docs/OWSGuide.html#_jnlp_file_association jnlp file association] for instructions on setting OpenWebStart as the default program for jnlp files.
     200
     201==== Testing Web Start ====#Webstarttest
     2021. Download [/download/josm.jnlp josm.jnlp] to your desktop.
     2031. Open a Terminal and move to the Desktop as above
     2041. Type `javaws josm.jnlp`⏎. This should initially download JOSM, show a security dialog and then launch JOSM.
     2051. If that fails, then type `javaws -verbose josm.jnlp`⏎. This should first show a dialog with information about the JVM and then launch JOSM.
     206
     207
     208=== Virtual Machine ===#Troubleshootingjvm
    75209==== Out of memory ====
    76 
    77 In more extensive edit sessions, you may get an "out of memory" error.
    78 
    79 To avoid this, the assigned memory can be increased with {{{-Xmx}}} option, see [[Help/CommandLineOptions]] for details.
    80 
    81 == Possibly outdated content below ==
    82 
    83 === Mac OS X errors ===
    84 [=#MacOSXMountainLionErrors]
     210Nowadays manually controlling Javas memory is seldom needed because available RAM on computers has grown.
     211Wrongly chosen values can decrease JOSM performance.
     212
     213For some tasks, JOSM has a large appetite for memory. On the one hand, it may be necessary to configure a memory size that supports more plugins and features. On the other hand can slow machines be stabilized by restricting Javas memory use.
     214If needed, use the [wikitr:/Help/CommandLineOptions command line] to set the [https://docs.oracle.com/en/java/javase/11/tools/java.html#GUID-3B1CE181-CD30-4178-9602-230B800D4FAE__BABHDABI Java Option] -Xmx…m, for example `-Xmx512m` or `-Xmx1536m`. In Debian/Ubuntu you can edit the file `/etc/default/josm` respectively `/etc/default/josm-latest`. \\
     215Formerly older java programs accepted `-Xmx=512m` or even `-Xmx 512m`. Now those malformed arguments throw error messages.
     216
     217==== VM selection ====#VMselectiononWindowsx64
     218On current versions of MS Windows by default Java is installed mainly in the `C:\Program Files\Java\` directory. Additional parts are placed in `C:\Program Files\Oracle\Java\`. There is a `.\javapath\` directory as target for the PATH environment variable. It is the home for the three virtual files `java.exe`, `javaw.exe` and `javaws.exe`. This files are symbolic links form the current Java installations.
     219
     220On older versions of 64 bit Windows sometimes the 32 bit mode JRE was additionally installed.  Also some browsers brought their own JVM with limited capabilities. In those cases a Web Start from the browser would not use your Java installation but that from the browser.
     221
     222Check that there's no other javawebstart in `\Windows\SysWow64`. The Java control panel will not detect it and you can safely delete it. Perform cleanup and only keep the latest versions of each JRE (One or the 32-bit mode, another one for the 64-bit mode).
     223
     224For shortcuts created on the desktop for JNLP and running the Javawebstart launcher , make sure to pass VM parameters prefixed with -J and no intermediate space before the VM option. If you have installed both the 32-bit and 64-bit version, you should pass the option "`-d64`" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!)
     225
     226Example of an edited command line for a shortcut on the windows desktop:
     227{{{
     228#!sh
     229javaws.exe -J-d64 -J-Xmx2048m  josm.jnlp

     236 * Registers JOSM.exe as target for the file extensions `*.osm`, `*.geojson`, `*.gpx`, `*.jos` and `*.joz`.
     237 * Places JOSM shortcut icons on the Desktop and in the Start Menu.
     238 * Adds uninstall data at the appropriate places.
     239
     240When starting, JOSM.exe starts JOSM with an embedded version of Java maintained by JOSM developers, based on Azul Zulu.
     241JOSM.exe acts as a ''wrapper'' and is [wikitr:/USB_Stick portable].
     242
     243HWConsole.exe is similar to JOSM.exe but start JOSM while keeping open a Windows console displaying JOSM standard output (logs).
     244
     245JOSM.exe accepts all usual [wikitr:/Help/CommandLineOptions#Programarguments JOSM Program arguments]. See example:
     246
     247{{{
     248#!sh
     249# Load OSM data
     250josm.exe https://www.osm.org/way/476702262
     251}}}
     252
     253For giving [wikitr:/Help/CommandLineOptions#Javaoptions Java options] to the Java VM, JOSM.exe uses the configuration file `JOSM.cfg` in its app sub-directory. In this file, each option must be on a separate line.
     254
     255For example, to change memory allocation, open `%LOCALAPPDATA%\JOSM\app\JOSM.cfg` and add `java-options=-Xmx8192m` (for 8 GB) to a new line under the `[JavaOptions]` header.
     256
     257==== Graphics ====#MicrosoftWindowsGraphics
     258Some Windows installations have graphics driver issues (see #23784 for an example). This may exhibit symptoms such as:
     259* Black bars in JOSM toolbars
     260* Flickering
     261* Other unexpected user interface issues
     262
     2631. Download and install Display Driver Uninstaller (DDU, [https://github.com/Wagnard/display-drivers-uninstaller source]) from the official mirror => https://www.wagnardsoft.com/display-driver-uninstaller-DDU-
     2642. From the "Device Type" drop-down on the right, select "GPU". DDU will automatically detect the GPU you're using.
     2653. Click on "Clean and Restart" at the top. This will uninstall the graphics drivers and restart your PC.
     2664. Reinstall the drivers.
     267
     268//**WARNING: Create a backup of your PC before using DDU. Although it creates a recovery point by itself, it's ideal to make one yourself just in case.**//

    89 [[Image(#8787:damaged_josm_app.png,align=right,margin-top=-35)]]
    90 Since Mac OS 10.8 a error message may appear on your first attempt to run JOSM:
    91 * older versions: ''JOSM.app is damaged and can't be opened. You should move it to the Trash.''
    92 * newer versions: ''JOSM.app can't be opened because it is from an unidentified developer.''
    93 
    94 To open JOSM for the first time, right-click on JOSM.app and confirm the opening in the pop-up dialogs. This is only necessary on the first run of JOSM.
    95 
    96 === openSUSE repository === #openSUSE
    97 
    98 Tested version of JOSM is available in the Application:Geo repository.
    99 
    100 First add as root user in yast or with zypper the repository (replace the version in the URL with the one you are using):
    101 {{{
    102 zypper ar -f http://download.opensuse.org/repositories/Application:/Geo/openSUSE_13.2 Application:Geo
    103 }}}
    104 
    105 Then simply install **josm** and **josm-fonts** package.
    106 
    107 === Ubuntu repository ===#Ubuntu
    108 
    109 This is a package repository primarily for Ubuntu. It should also work with other Debian based (especially Ubuntu based) distributions, but we do not actively test and maintain any distributions other than Ubuntu.
    110 [[BR]]
    111 Note: in addition to the regular procedure described below, older DEBs can be manually downloaded and clicked to be installed from the following directories:   [https://josm.openstreetmap.de/apt/pool/universe/j/josm/ for josm]  [https://josm.openstreetmap.de/apt/pool/universe/j/josm-latest/ for josm-latest] 
    112 
    113 The repository contains two packages:
    114  {{{josm}}}:: ''The tested version''[[br]]
    115   Replaces the package from the official Ubuntu repository.
    116  {{{josm-latest}}}:: ''The development version (nightly build)''[[br]]
    117  Can be installed parallel to the {{{josm}}} package. The default preference folder is {{{~/.josm-latest}}}.
    118 
    119 ==== Installation ====
    120 
    121 Edit the package resource list {{{/etc/apt/sources.list}}}:
    122 
    123 {{{
    124 #!sh
    125 sudo editor /etc/apt/sources.list
    126 }}}
    127 
    128 and add one of the following lines according to your Ubuntu-Version:
    129 
    130 {{{
    131 deb https://josm.openstreetmap.de/apt lucid universe
    132 deb https://josm.openstreetmap.de/apt precise universe

    140 deb https://josm.openstreetmap.de/apt xenial universe
    141 }}}
    142 
    143 Alternatively, this can  be done with the following one-liner:
    144 {{{
    145 echo deb https://josm.openstreetmap.de/apt $(lsb_release -sc) universe | sudo tee /etc/apt/sources.list.d/josm.list > /dev/null
    146 }}}
    147 
    148 For other Debian based distributions, add the following line:
    149 
    150 {{{
    151 deb https://josm.openstreetmap.de/apt alldist universe
    152 }}}
    153

    169 Now refresh your sources
    170 {{{
    171 #!sh
    172 sudo apt-get update
    173 }}}
    174 and install:
    175  {{{josm}}}:: (You can skip the first line if you haven't installed these packages before.)
    176 {{{

    187 
    188 === VM selection on Windows x64 ===
    189 
    190 For Windows, beware that some browsers may install their own JRE only in 32 bit mode, but may also install their version of the Javawebstart tool somewhere else with different file associations. This may cause your JNLP to start with this alternate JRE because it runs the wrong version of Javawebstart which only supports the 32 bit VM, and sometimes is built with a restricted support for VM options and a max VM size not exceeding 256MB.
    191 
    192 Check, for example, if there's no other javawebstart in {{{\Windows\SysWow64}}}. You should not need it (the Java control panel will not detect it) and can safely delete it. Perfom cleanup and only keep the latest version of the JRE (1 for the 32-bit mode, another one for the 64-bit mode).
    193 
    194 For shortcuts created on the desktop for JNLP and running the Javawebstart launcher (from {{{\windows\system32}}}), make sure to pass VM parameters prefixed with -J and no intermediate space before the VM option. If you have installed both the 32-bit and 64-bit version, you should pass the option "{{{-d64}}}" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!)
    195 
    196 Example of an edited commandline for the shortcut created on the windows desktop after running JOSM just once from the JNMP and exiting:
    197 {{{
    198 #!sh
    199 C:\Windows\System32\javaws.exe -J-d64 -Xmx=2048m -localfile -J-Djnlp.application.href=https://josm.openstreetmap.de/download/josm.jnlp "C:\Users\<snipped user name>\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\21\7311<snipped-hex-number>7f8"
    200 }}}
    201 You don't need to change the end of the command line with the snipped parts here. Just check the path for {{{javaws.exe}}} and add options {{{-J-d64}}} for the 64-bit mode needed to work with large OSM datasets, and {{{-Xmx=2048m}}} to increase the VM size (to 2GB here).
