Thank you for your reply and explanation (and no worries, your English is perfectly understandable!). I'm sorry to hear about the troubles, but I'm glad to hear that at least a fresh installation worked.
It would have been interesting to see if the main snapd service and other related services were running okay in the environment before/during upgrade, using commands like: systemctl status snapd.service systemctl status snapd.apparmor.service And also have a look at their logs. But considering you likely no longer have access to the environment (due to reinstalling) we can't find that out. Since this seems like a possible snapd issue rather than a firefox one, I'll reassign the bug accordingly. Thanks again. ** Package changed: firefox (Ubuntu) => snapd (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2078413 Title: package firefox 1:1snap1-0ubuntu2 [modified: usr/bin/firefox usr/share/applications/firefox.desktop] failed to install/upgrade: le sous-processus nouveau firefox paquet pre-installation script a renvoyé un état de sortie d'erreur 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2078413/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
