DinoX requires Ubuntu 24.04+ because it uses modern GTK4/libadwaita which needs GLIBC 2.38+.

The AppImageHub CI tests on Ubuntu 22.04 (jammy), which has GLIBC 2.35. This is a fundamental incompatibility.

Ubuntu 22.04 Desktop support ends in April 2025 (5 months). I would suggest updating the test environment to Ubuntu 24.04 to support modern GTK4/libadwaita applications.

DinoX AppImage works perfectly on Ubuntu 24.04+ and can be downloaded directly from:

Thank you for your time.

Ubuntu 22.04 Desktop support ends in April 2025 (5 months).

Please resubmit your application in 5 months then. We bump the version that is used for testing whenever the oldest still-supported version changes, in order to make sure no "too new" dependencies end up in the catalog. Thanks!
