Oh, I managed to fix this. Here's what I've done: 1. Reboot 2. Switched to TTY, without login in in GNOME 3. sudo ubuntu-drivers autoinstall 4. Manual cleanup/purge of old packages.
The weird thing: This is already the second time this happened on this computer. Previously I fixed it by booting from the installer, chrooted into my system and reinstalled all the kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1737133 Title: package linux-image-4.13.0-19-generic 4.13.0-19.22 failed to install/upgrade: subprocess installed post-installation script was killed by signal (Terminated) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1737133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
