Fallout 3 GOTY install fails on PopOS 22.04

[MkMan]

Hi,

I am having trouble installing MO for Fallout 3 GOTY on PopOS 22.04. protontricks installed using flatpak from Pop!_Shop. Steam and the game are installed in the default location.

When I run the install script it finds the Steam library but not the game.

mustafa@mustafa-desltop:~/Desktop/mo2installer-5.0.3$ ./install.sh 
INFO: all dependencies met
INFO: selected game 'fallout3_goty'
INFO: found Steam in '/home/mustafa/.local/share/Steam'
INFO: game not found in '/home/mustafa/.local/share/Steam'
INFO: steam not found in '/home/mustafa/.var/app/com.valvesoftware.Steam/.local/share/Steam'
ERROR: could not find any Steam library containing a game with appid '22370'. If you known exactly where the library is, you can specify it using the environment variable STEAM_LIBRARY

I then follow its suggestion and manually set the STEAM_LIBRARY var making the command STEAM_LIBRARY="/home/mustafa/.local/share/Steam" ./install.sh (I also tried without the " around the path). It then downloads the files but fails when creating a backup of the launcher.

What am I missing?

Thank you
