I’m on Linux Mint 22.2, trying to update Project Zomboid to a beta version, and when Steam gets to the ‘validating’ part of the update it hangs. The content_log.txt file shows the following:
[] GetCellList - failed to get AppData for WinUI
[2025-09-30 17:04:24] Load failed: /home/USERNAME/.steam/debian-installation/steamapps/libraryfolders.vdf.
[2025-09-30 17:04:24] Load failed: /home/USERNAME/.steam/debian-installation/config/libraryfolders.vdf.
The ‘GetCellList’ error repeats a bunch so I’m assuming that’s where it’s hung up, but I wasn’t sure if the ‘load failed’ messages were relevant so I included them too.
I’ve tried restarting Steam, my computer, and internet comments suggested deleting the files that are causing the problem, but when I temporarily moved them to the trash that didn’t fix the issue (they’ve been restored now). Any ideas for next steps would be greatly appreciated! Please let me know if I need to be adding any more info from different log files.
