Public bug reported: A couple hours ago, Firefox crashed on me for seemingly no reason. A flashplugin-installer error dialog popped up, which I dismissed without reading. I'd seen a similar dialog that said "flashplugin-installer failure to download extra data files" a few times before and had been ignoring it because I had been unable to fix it.
When I restarted Firefox, I discovered it would crash on startup every time. After trying a few different ways to get it running, I discovered the cause was a Bus Error, and that neither starting with a fresh profile nor starting in safe mode would help. Looking through /var/log/apt/history.log, I noticed an unattended-upgrade which corresponded to about the time that Firefox first crashed. The important bit seemed to be: flashplugin-installer:amd64 (27.0.0.159ubuntu0.16.04.1, 27.0.0.170ubuntu0.16.04.1) I don't really use flash much, so rather than figure out how to downgrade, I just tried `sudo apt purge flashplugin-installer`, and Firefox started fine after that. For me, the problem is solved, but I wanted to report the bug in case it still affects others. ** Affects: flashplugin-nonfree (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724683 Title: Firefox crashes on startup after updating to flashplugin- installer:amd64 27.0.0.170ubuntu0.16.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/1724683/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
