Hello, Sorry for the slow reply here. As the dpkg terminal log suggests, a newer snapd and core snap were needed before trying to install the firefox snap. Did you try that at the time? I believe snapd should have figured that out itself, and if it didn't at the time, it may be fixed since then.
Are you able to reproduce this still? If not, we should probably close this bug. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2025135 Title: package firefox 91.0+build2-0ubuntu0.20.04.1 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/2025135/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
