Fresh install 8.1.0, never used. Installed from Flathub on Arch with KDE, updated as of 3/10/2025. Launching from terminal yields:

This could be a packaging problem. Uninstalling from Flatpak and installing AUR tribler-bin succeeds.

[qstokkink]

First things first, what is causing this error is that the database file cannot be written to your user "home" directory.

What I see from https://github.com/flathub/org.tribler.Tribler/blob/master/org.tribler.Tribler.yaml#L20, is that --persist=.Tribler is being used. My intuition would be that the Flatpak does not have permission to write into your ~/.Tribler directory. Changing your directory permissions should resolve that.

If that doesn't solve your issue, this issue should probably be moved to https://github.com/flathub/org.tribler.Tribler then.

Thanks for the fast response. I was mainly just testing Tribler and decided to ultimately uninstall. I'll close the issue and others can resume if the above doesn't help them.
