Hello, I realize it's pretty late now (apologies for that) but do you happen to have the systemd journal logs from the time of this failure? Could you reproduce this issue today if you were to attempt another upgrade on a similar system with up-to-date packages? Also, were there any non- typical system configuration aspects? Otherwise I'm afraid there's not much details to go on by to try and debug this.
Thanks. ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038391 Title: package firefox 118.0.1+build1-0ubuntu0.20.04.1 failed to install/upgrade: new firefox package pre-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/2038391/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
