SNAP crashes shortly after start

ESA's Sentinel Application Platform GUI usually crashes shortly after it is started on a virtual machine. The problem are missing 3D drivers that are needed for the Worldwind plug-in.

In order to be able to use SNAP, the Worldwind plug-in needs to be disabled. This plug-in is usually located in the .snap directory in the users' home folder.

You can move the file to a different location if you would like to keep it as a backup. Open a Terminal/Console and run the following command:

1 mv ~/.snap/system/modules/org-esa-snap-snap-worldwind.jar ~/

Alternatively, you can delete it for good:

1 rm -rf ~/.snap/system/modules/org-esa-snap-snap-worldwind.jar

Upon the next startup of SNAP, you will receive a message saying that some modules are not available. Click "Disable Modules..." to continue.

Please note that you might need to perform this tasks after every update of the SNAP software.

The commands shown above might fail if the location of the plug-in differs. You can find the location with the following command.

1 find / -iname "org-esa-snap-snap-worldwind.jar"

If the plug-in is enabled system-wide, or in a directory where you don't have access to,  please contact your administrator to help you. The module might be located somewhere in /opt/snap, /usr/local/ or /etc.
