ad #3 (continued): attempt to de - install kernel 4.15.0-21: not possible to de - install the image 4.15.0-21! Removed the .postrm and .generic.list files, related to this kernel, in /var/lib/dpkg/info/ in order to be able to get "apt" working.
Found 4.15.0-20~16.04 (version april 25) in /xenial-proposed -> installed it -> wifi works -> three consecutive boots were successful -> other than 4.15.0-21, kernel 4.15.0-20~16.04 could be de -installed without any problems. -- 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
