Your new 'allpackages.txt' shows the same problem as before. To verify the problem is fixed you should at least be able to run:
dpkg -l | grep oibaf and get ZERO results. I understand the evolution of this bug and your attempts to fix it. What I am saying is that you have now broken the machine to the point where we can't fix it or offer more support. The only real bug you are likely experiencing is still bug 1727356. There is a workaround documented in bug 1727356 you can use, or you can install a newer build like from http://cdimages.ubuntu.com/bionic/daily- live/current/ which should completely avoid the bug from the beginning. Also remember to avoid installing any PPAs so that we can support you in future. -- 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
