Support for Shell Extensions was removed from GNOME Software since 3.36 (because it was problematic and hard to maintain). I just checked it in the latest stable Snap Store app and was not able to find any support for Shell Extensions there.
So, I see three possible solutions for this issue: 1. Add downstream support for Shell Extensions to GNOME Software / Snap Store on Ubuntu. (That would bring too much work and possible issues, at least in my opinion.) 2. Add AppStream metadata file to the chrome-gnome-shell package that would display the package as Add-on for something (Firefox?) in Snap Store. 3. If a package from main cannot depend on a package from universe, move gnome-shell-extension-prefs to universe and add chrome-gnome-shell to its dependencies. (That would be the best solution in my opinion.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866841 Title: Add chrome-gnome-shell to ubuntu-desktop recommends To manage notifications about this bug go to: https://bugs.launchpad.net/hundredpapercuts/+bug/1866841/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
