Note that if you have previously tried and failed to launch the AppImage, you may need to remove Plexamp’s existing settings before parameters like --no-sandbox will allow Plexamp to launch:

Per https://forums.plex.tv/t/plex-amp-3-01-on-ubuntu-16-04-just-displays-a-blank-screen-on-start/580342/26:

Deleting everything under ~./config/ seems like a bit of a nuclear option… maybe try removing just the program’s settings instead. :wink:

After some tinkering, I have managed to get Plexamp running on Ubuntu 20.04 LTS with these steps:

  1. Delete any existing Plexamp configuration to start over from scratch, just in case.
    (rm -rf ~/.config/Plexamp/)
  2. Launch Plexamp with the --no-sandbox parameter using the CLI of your choice and sign in
  3. Optionally, add the parameter to your system’s relevant *.desktop file to make running Plexamp a little easier in the future.

To always launch Plexamp with sandboxing disabled, add the --no-sandboxparameter from Step 2 to the first Exec= line in the Desktop Entry section:

[Desktop Entry]
Name=Plexamp
Exec=/path/to/Plexamp.AppImage --no-sandbox
Terminal=false
Type=Application

Now, you can start Plexamp without using the CLI at all.

Note: Desktop files are what make launcher shortcuts work; they’re usually stored in ~/.local/share/applications/… just look for a file with Plexamp in the name.
