[Bug 2083496] [NEW] Installation of Fuse for AppImage Support Causes GDM Failure

[Alexander La Barge]

Public bug reported:

Installing fuse on Ubuntu 24.04 removes `ubuntu-session`, leading to a
broken GDM on reboot

Steps to reproduce:
1. Install fuse on a fresh Ubuntu 24.04 system:
   
   sudo apt install fuse

2. Reboot the system.

Expected behavior:
GDM should start normally without issues after the reboot.

Actual behavior:
On reboot, the system gets stuck at the `stop plymouth` and `start gdm` parts of the boot process, making it impossible to reach the login screen.

Workaround:
To fix this issue, I had to:
1. Switch to a different TTY, log in and execute following commands:
   sudo apt remove fuse
   sudo apt install ubuntu-session
   sudo reboot
2. If `fuse` functionality is needed, install `fuse3` instead:
   sudo apt install fuse3

Additional notes:
- Installing `fuse2` seems to break the system by removing `ubuntu-session`, which is critical for `gdm` and the GNOME desktop environment to function properly.
- It's unclear why `fuse2` is still the default when using `apt install fuse`, as it breaks the session manager and leads to this boot issue.

Recommendation:
Package fuse2 be updated for 24.04 to conduct GDM sanity check/ resolve dependecy errors for ubuntu-session being removed during installation process.
