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 Desktop Packages, which is subscribed to firefox in 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 Status in snapd package in Ubuntu: New Bug description: Hormis le fait que Firefox n'était pas géré par snap mais par synaptic, je ne vois pas de raison d'avoir un bug. je suis en dual boot avec Windows et le fichier de configuration de firefox est dans un répertoire dédié.
