Looks like the sbverify command failing is not relevant. Retrying to boot with secure boot enabled in BIOS _after_ I downgraded shim/shim-signed to the versions that are in the archive for Xenial(updates pocket) was successful and brought up mok manager once, allowing to again disable secure boot at that stage (since I still need to use some DKMS packages and want to try test kernels). So the main problem were those incorrect versions:
shim 0.9+1474479173.6c180c6-0ubuntu1 -> 0.8-0ubuntu2 shim-signed 1.21.4~14.04.1+0.9+1474479173.6c180c6-0ubuntu1 -> 1.19~16.04.1+0.8-0ubuntu2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652147 Title: UEFI secure boot fails after 14.04 to 16.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1652147/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
