Describe the bug

Error on installing on Ubuntu 24:

The following packages have unmet dependencies:
  appimagelauncher: Depends: libgl1 but it is not installable
                    Depends: libfontconfig1 but it is not installable
                    Depends: libharfbuzz0b but it is not installable
                    Depends: libfribidi0 but it is not installable

My guess: Ubuntu 24.04 renamed a bunch of core libraries as part of a technical transition (e.g. libfontconfig1 → libfontconfig1t64). AppImageLauncher's normal downloadable .deb was built before that rename, so it's asking for library names that no longer exist under those names on your system - even though the actual libraries are installed.

Expected behavior

Seamless install

Steps to reproduce the issue

1. download .deb from releases
