OMG, Your comment: "#19 and forward assume..." Points into the right direction. When I install the "good" kernel-DEBs You provided the problem pops up... This happens although the "real" kernel deb (linux-image-unsigned-5.3.0-61-generic_5.3.0-61.55_amd64.deb) was not installed due to conflicts against my signed kernel of the same version.
I then compare the snapshots made by SystemBack of these two versions. There are a lot of differences mainly the initrd (in boot) and althougth all *.ko inside modules. I remember that every try to install something that resuts in a kernel update (dkms and/or update-initrd) the problem ocurs. I therefore do a manual sudo update-initramfs -k all -u without installing anything else. -> Problem pops up! This happens even when I use my oldest system snapshot I have :-( So how to proceed ? (I am thinking about doing a fresh install of Ubuntu 20.4 LTS, but have to check if all tools I use will be available... FreeCad wasn't the first time I checked). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888570 Title: poweroff not working after apt upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1888570/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
