When you upgrade from one version of Ubuntu to the next, PPAs are disabled, because there's no way to ensure that the PPA contains packages for the version you're upgrading to. That's an expected behaviour.
The quote means that issues with firefox-esr from Jonathon's PPA should be reported to him, not as bugs against the official ubuntu package. I suggest you contact Jonathon (https://launchpad.net/~jonathonf/+contactuser) to discuss the issue with him. Feel free to engage in a conversation with him here, even though the bug is invalid it might be useful to others who use that PPA. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1812057 Title: Upgrade Lost Firefox ESR To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1812057/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
