This bug and there is no bug started in Mint 20.1 with Kernel 5.12-rc7 alongside the shim 1.46 multiple issues. Since then it works here secure boot enabled or not.
The bug comes with a broken header and it kills update manager. All we do here to make it work is to delete the broken header in Synaptic, After, update manager runs normally. Same for the Kernel with 3 deb packages only. Give it a try, there is no side effect. If you don't want me to test mainline Kernel in Mint (noise free), then you have to remove the second header. We never give up no matter what the problem is, even with 3 legs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926938 Title: Recent mainline packages are built with Hirsuite 21.04, not Focal 20.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
