Hello, and thank you for the bug report. Unfortunately I don't have any specific ideas about this, so I would check if you have an up-to-date version of snapd (which per the DpkgHistoryLog.txt attached to your report I believe you do), and also if you're able to reproduce this repeatedly/reliably if you were to attempt the upgrade again on the same system or another system?
Also since this appears to be a snapd bug I'll reassign it there. Thanks. ** 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/2078069 Title: package firefox 129.0.2+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/snapd/+bug/2078069/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
