The reasons to why old kernels are not intentionally being marked for autoremoval (as of 2008-11-04) is because it was considered too dangerous, and apt has an exception to not tag linux-image-* packages for autoremoval because _we_ had no idea which kernels actually worked for a system.
However, I had thought that this problem had been addressed using last- good-boot for grub after runlevel 2 was reached, here: https://wiki.ubuntu.com/KernelTeam/removing-old-kernels But since the wiki hasn't been updated since '08, maybe that is not true anymore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1439769 Title: various linux packages being marked as manually installed, still prevents 'apt-get autoremove' from doing the right thing for kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/1439769/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
