Agreed. Except I would say "definitely". It's important that Ubuntu gets some sort of a fix soon. I've already seen a person asking on a forum how to downgrade and being told to install a third party package by hand. This is no better, and possibly worse from a security perspective. Seth also writes, "None of the upgrade tools are in a position to check architecture features before installing a package. There may not be a happy solution here." Again, I agree, the solutions I'm coming up with are not particularly happy. However, a solution is needed. In the short term, switching to ESR (as mentioned above) would let Firefox work on all supported architectures and have security updates. For the long term, well, I don't want to clutter up this bug — which is about an urgent problem needing an immediate solution — so I've filed Bug 1698501. I'll continue my response there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697800 Title: [regression] firefox dies with SIGILL on machines without SSE2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1697800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
