❌ Test failure

@esoltys: 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 2.35

• 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

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.

[esoltys]

Luminous deliberately stopped shipping an AppImage after v0.99.1 because of an upstream Tauri/WebKitGTK EGL issue (the bundled graphics stack collides with the host's, giving a blank window), so the 0.99.1 build this found is stale and known-broken. Linux users should use the .deb/.rpm or Flatpak from the releases page.

Please close.

Hi @esoltys, thanks for your response. Do you happen to know a Tauri GitHub Issue describing this situation? I would like to help them produce properly working AppImages. It can be done.

tauri-apps/tauri#11988

[Edit]

• tauri-apps/tauri#15665 (July 2026): default AppImages fail on distros with Mesa 25 or newer because the bundler packs in too many libraries.
• tauri-apps/tauri#15976 (September 2026): reports the exact EGL_BAD_PARAMETER crash from bundled libwayland/libxkbcommon/libxcb on newer Mesa. A maintainer made this the tracking issue for the EGL problem.
• tauri-apps/tauri#10749 (2024): similar Fedora 40 failure, closed as not planned. tauri-apps/tauri#5143, the general "blank screen" issue, is still open.

Oh, maybe it's been fixed by tauri-apps/tauri#16062 From a few days ago. Hmm.

Feature: Restore AppImage distribution with GPU rendering (Tauri CLI 2.12 fix)

[esoltys]

Yeah, builds for both Wayland and X11 look good. I'll have an AppImage in the next release and I'll post it here.

❌ Test failure

Tested:

• Luminous.Music.Player_3.0.0_amd64.AppImage from release v3.0.0

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

• The AppImage needs a newer C library (glibc, or the C++ library libstdc++) than the test system has; the error names the version that is missing (e.g. GLIBC_2.38). The test runs on the oldest Ubuntu LTS release that is still in standard support (see https://ubuntu.com/about/release-cycle), because an AppImage is meant to run on any current Linux distribution, including older ones, and glibc can only be as old as the system the AppImage was built on: a program built on a newer system links against symbols that older systems do not have. The fix is to build on the oldest still-supported LTS release (in GitHub Actions, the oldest ubuntu-* runner still offered, or a container of that release), not on the newest system. If the program itself needs a newer compiler, build in a container of the old release with a newer toolchain (e.g. the toolchain PPAs), statically link what needs it, or bundle the C library together with its dynamic loader (ld-linux) in the AppImage: then the host's glibc does not matter at all (the test reports X-AppImage-Libc=bundled). See https://docs.appimage.org/reference/best-practices.html#binaries-compiled-on-old-enough-base-system
• 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.

Hmm. I'll have to look in to changing my workflow to build on ubuntu-22.04 instead of ubuntu-24.04 for the appimage. I'll see what I can do.

✅ Test passed

Please check that the screenshot shows the application's main window.

Luminous

Tested:

• Luminous.Music.Player_3.0.0_amd64.AppImage from release v3.0.0

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

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
