❌ Test failure

Tested:

• Geminus_1.0.1_amd64.AppImage from release v1.0.1

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.
• AppRun.wrapped (or the launcher it starts) could not be executed. This typically happens with Tauri and linuxdeploy builds when a cached launcher was packaged with mode 0770 and is owned by root, so that it is not executable for the test user. Please make the AppDir readable and executable for everyone before packaging, e.g. chmod -R a+rX AppDir (and chmod a+x on AppRun and AppRun.wrapped) before running appimagetool.
• The application quit or crashed right after starting; the error below usually shows why. Note that the test runs the application without network access, on purpose, and that this is a requirement for the catalog: an AppImage must start without network (users are offline too). If the application needs a server, a login or an update check to start, please make it show its window (or at least a message) first and connect afterwards, and handle a failed connection instead of exiting.

First error in the log:

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

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.
