ValueError: Invalid bus name 'firefox': must contain '.'

It seems there’s something wrong with fedora-38. After the last update, if I try starting firefox from the menu or using a shortcut, it doesn’t start and I get this in systemd journal:

If I switch the VM to fedora-37 template, that works fine. I can still start terminal and start firefox that way, that works too. Interestingly enough, other applications (e.g. thunderbird) seem to start fine.

BTW I’m on qubes 4.1.2.

Add fallback for invalid bus names

Probably these 2 topics can be combined as they are on the exact same problem:

Last Template-Fedora38 update broke Firefox

Last template fedora 38 update broke firefox in all fedora based app-VM’s. Firefox can only be started from terminal since last update. [Screenshot_2023-10-06_14-22-54]

I agree. I have searched for the same issue, but I failed to notice the one create a bit earlier.

Last Template-Fedora38 update broke Firefox

Solved by using dnfdragora in the fc38 template. removed firefox with dnf, and manually remove firefox from /usr/lib64/ using sudo rm -rf. Did this in ALL fedora based app VM’s. And doing sudo dnf clean all in the template, the services and the app VM’s including default-dvm. Really everywhere. All of this untill firefox is completely removed in everything based on Fedora. Say NO to every update to Firefox 118. When it is really gone, reboot. Go to dnfdragora and install firefox 111. That fire…

Last Template-Fedora38 update broke Firefox

I wouldn’t install a severely outdated version (that no longer gets any security patches) just to fix this temporary inconvenience of having to start Firefox through a terminal.

Last Template-Fedora38 update broke Firefox

To fix the launcher problem right now, people can remove the line DBusActivatable=true in /usr/share/applications/firefox.desktop on their Fedora TemplateVM.
