Thanks Mr. Forshee, that was the problem. Before you close this bug, could i ask a clarification question.
I followed the steps here: https://help.ubuntu.com/community/RemoveOldKernels apt-mark showauto 'linux-image-.*' showed: linux-image-lowlatency-hwe-20.04 And apt-mark showmanual 'linux-image-.*' showed: linux-image-5.8.0-43-lowlatency linux-image-5.8.0-45-lowlatency linux-image-5.8.0-48-lowlatency linux-image-5.8.0-49-lowlatency linux-image-5.8.0-50-lowlatency What i did was i marked all but linux-image-5.8.0-50-lowlatency as autoinstalled and then sudo apt autoremove --purge. My questions are: 1. Should i also mark linux-image-5.8.0-50-lowlatency as autoinstalled; 2. Do you think it is normal/correct to have so many linux-image-* packages marked as manually installed? I don't remember setting all of these/installing them manually. I believe in the past i have purged old linux-image-* packages which were some 5.4-lowlatency and then installed linux-image-lowlatency-hwe-20.04, but IMO all these linux-image-* packages should've been automatically removed as part of the numerous previous kernel updates i received. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925783 Title: installed linux-firmware package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1925783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
