[Bug 1717878] Re: gdm3/gdm-session-worker crashed with SIGTRAP logging "GdmSession: no session desktop files installed, aborting..." from get_fallback_session_name from get_default_session_name from get_session_name from get_session_filename from gdm_session_is_wayland_session

[Andrew Gree]

I don't see a fix. The exact scenario happened to me just yesterday:

- AppImage told me to install fuse
- apt install fuse
- crash, purge reinstall needed for gdm3
- correct fuse (fuse3) is installed upon purge

we need gdm3 to actively prevent installing incorrect fuse version, OR
require entire ubuntu-desktop be uninstalled if user needs incompatible
fuse

please reopen

  This crash occurs when you uninstall all session files (by accident)
  from the system. One common way this can happen is by trying to
  install 'fuse'.

  To fix it just run:

    sudo apt install --reinstall ubuntu-session

  or whatever-session for your preferred Ubuntu flavor.
