❌ Test failure

@Dudude-bit: this pull request adds the AppImage from your GitHub repository to the AppImage catalog; the test reports the following. Could you have a look?

Compatibility: not self-contained: uses the C library of the system; references glibc 2.39

• A file inside the AppImage is not executable. Please check the file permissions before packaging the AppImage.
• The application quit or crashed right after starting. The error below usually shows why.

First error in the log:

/run/firejail/appimage/AppRun: line 12: /run/firejail/appimage/AppRun.wrapped: Permission denied

The application showed no window, but may be a system tray application (usr/lib/girepository-1.0/Gtk-3.0.typelib: gtk_status_icon_new); running it again with a system tray
/run/firejail/appimage/AppRun: line 12: /run/firejail/appimage/AppRun.wrapped: Permission denied
No icon appeared in the system tray either
ERROR: The application exited within 11 seconds instead of showing a window

What next: once the AppImage is fixed (e.g. in a new release), comment /retest here to test it again. If it should not be in the catalog after all, close this pull request; an app that is already in the catalog can be removed by a maintainer with /remove.

/retest

4.21.1 fixes it: the launcher inside the AppImage (AppRun.wrapped) was stored as 0770, so a user other than the mount's owner could not start it (tauri-apps/tauri#16155).

❌ Test failure

Compatibility: not self-contained: uses the C library of the system; references glibc 2.39

• The AppImage was built on a system that is too new. Please build it on the oldest still-supported Ubuntu LTS release so that it runs on all supported systems.
• The application quit or crashed right after starting. The error below usually shows why.
