❌ Test failure

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

• The AppImage is missing a required file (see below). See https://docs.appimage.org/reference/appdir.html for what an AppImage must contain.

First error in the log:

FATAL: .DirIcon is missing in /tmp/.mount_runtimdhemic

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.

❌ Test failure

Tested:

• tmuxy_0.0.10-alpha.72_amd64.AppImage from release v0.0.10-alpha.72 (the name looks like a pre-release)

Compatibility: not self-contained: uses the C library of the system; references glibc 2.35

Notes:

• File name 'tmuxy': all-lowercase names are typically used for command line tools, but the desktop file does not set Terminal=true. If this is a graphical application, please name the file after the application as it is spelled, with capitals where it has them (e.g. 'Krita'); if it is a command line tool, set Terminal=true in its desktop file.

• The application quit or crashed right after starting. The error below usually shows why.

First error in the log:

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.

tmuxy

Tested:

• tmuxy_0.0.10-alpha.73_amd64.AppImage from release v0.0.10-alpha.73 (the name looks like a pre-release)

Compatibility: not self-contained: uses the C library of the system; references glibc 2.35

Notes:

• File name 'tmuxy': all-lowercase names are typically used for command line tools, but the desktop file does not set Terminal=true. If this is a graphical application, please name the file after the application as it is spelled, with capitals where it has them (e.g. 'Krita'); if it is a command line tool, set Terminal=true in its desktop file.

Warnings:

• The AppImage contains no update information, so users cannot update it with AppImageUpdate or similar tools. Please consider embedding it when building the AppImage (e.g., appimagetool -u) and publishing the .zsync file next to the AppImage; see https://docs.appimage.org/packaging-guide/optional/updates.html
