Unfortunately 'allpackages.txt' shows you do still have PPAs from "oibaf" installed. To check that more easily you should be able to run something like:
dpkg -l | grep oibaf If you are unable to remove/downgrade all those using 'ppa-purge' then I can only recommend that you reinstall Ubuntu from scratch. Then just remember to use the workaround in bug 1727356 until your system is fully updated with the proper fix and everything should just work [TM]. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810630 Title: Boot up is hung on a purple screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1810630/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
