ad #3: earlier today, I have tested the kernel 4.15.0-21 under lubuntu-16.04, taken from ppa:canonical-kernel-team/ppa.
So far, 3 consecutive boots without problems. I will report back after I have de - installed this kernel again, and have replaced it by what I find in xenial-proposed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767133 Title: linux-image-4.15.0-20-generic install after upgrade from xenial breaks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1767133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
