Please install a few old kernels manually, mark them autoremovable and run u-u in verbose and debug mode.
If u-u removes those kernels this is not an u-u bug. Then install those again and try removing them with apt. If apt removes those kernels than this is not an APT bug. ** Changed in: unattended-upgrades (Ubuntu) Status: New => Incomplete ** Changed in: apt (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1914278 Title: apt autoremove is not removing unused kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1914278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
