Arch Linux User Repository

Yeah maybe. I just tested this on a fresh VM but I'll try to take a closer look at it later tonight. Thanks!

I'm on Arch + yay too, not sure what your setup might be but the problem seems to be related to the fakeroot: AppImage tries to use root-owned directories and buses and obviously can't, while with my fix it will try to use the regular user-owned ones and therefore succeeds. Maybe you have something configured that makes AppImage play nice with fakeroot.

Hi there! Thanks for tracking this down. We're in the middle of releasing a game and I'm a bit overwhelmed atm.

Are you both using Manjaro? It seems to work fine on Arch + yay.

Thanks!

I found the problem!!

The AppImage --appimage-extract operation fails because it's done inside of the package() function, which is run in the fakeroot. Instead, the extract step should be run during build(), which is run by the local user.

The following is the diff I get from git when updating the PKGBUILD to work this way:

Similar issue as @Darkhogg

Using manjaro with yay.

I'm having the same problem @thunderingMarmot described, with the following logs:

==> Starting package()...
QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0

and the "Failed to register AppImage in AppImageLauncherFS: error while trying to start appimagelauncherfs.service" popup dialog.

This is all happening with the --appimage-extract command, which is weird because I have other AppImage packages installed (I maintain one myself, even) that give me no such problems.

Hey, md5sum is incorrect

The UnityHub source location has changed, and the validity check isnt working for me.
