A small, self-hosted place for a group of friends to hang out. Text+Voice rooms, presence, and file sharing. One person runs a server, your friends connect. Nothing to sell you. No company in the middle.

✅ Test passed

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

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

Linger

Tested:

• Linger_0.5.1_amd64.AppImage from release v0.5.1

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

Warnings:

• The window is mostly dark, so the application seems to start in a dark theme although the test system is not set to dark mode. Please use a light mode by default and use the dark theme only when the system is configured for dark mode (e.g. the GTK/Qt or theme setting) or the user chooses it in the settings.
• The screenshot may show an error message; please check it.
• 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

Commit e7409ea. Full log

[itsMattGuenther]

Here's Linger's main window once you've joined a server: the buddy list, with a room open beside it.

From the next release, the AppImage carries an AppStream metainfo file that names this screenshot, so the catalog page can show it instead of the join screen. I'll comment here when that release is out.

Why does it come up in dark mode?

[itsMattGuenther]

Linger only has a dark look, on purpose: there's no light mode, so it opens dark whatever the desktop's theme is. Thanks for adding it to the catalog!
