Hello @plytkachodnikowa, there's a lot of Failed to write app state file "/drives/hdd/Gayms/SteamLibrary/steamapps/appmanifest_* lines in your content_log.txt. Can you check if the filesystem the secondary Steam library folder is using is healthy and that your regular user has read/write permissions?
That's an unrelated drive. The drive causing problems here is mounted as /drives/hdd3.
No, it isn't an unrelated drive because Steam is trying to use it for staging the game updates with lines like [2025-06-29 20:47:54] AppID 553850 update canceled : Staging folder not writable (Disk write failure) "/drives/hdd/Gayms/SteamLibrary/steamapps/downloading/228980" in your content_log.txt.
That's weird. My understanding was that steam stages the game updates on the drive where the game is located. Anyways, filesystem is healthy and permissions appear correct. This however changes the circumstances as it would mean the issue may be related to NTFS
In my experience, Steam doesn't work well with btrfs, unfortunately. Something weird is going on. I had issues like https://github.com/ValveSoftware/steam-for-linux/issues/10606 that fully disappeared after converting my /home partition from btrfs to ext4.
I know it's easier said than done, but maybe try converting to ext4 and see if the problem persists. I'm sure it would help Valve find the root cause.
Issue magically disappeared after removing the library on /drives/hdd from the steam client.
Your system information
Please describe your issue in as much detail as possible:
Expected behavior: game patches normally and update succeeds
current behavior: after clicking update, game begins to update, ad when it gets to the patching step, it hangs there for 2 seconds, then craps out with "disk write error", running steam via the commandline shows an absolute lack of any related logs. Likely related to filesystem/library location? (btrfs, library is on separate drive)
Steps for reproducing this issue:
Extra info:
Bug seems to only affect game updates with patching step, installing, uninstalling, moving, updating for games that don't have the patching step, and playing all work perfectly fine.
