This bug can probably be closed now. Feedback for other reading this: 1. After rebooting the mok management was shown 2. It rebooted by itself after a minute or so 3. No password was entered, even though it was asked twice by configuration of the shim-helpers package to enter such a password 4. The machine boot sequence continued 5. Once booted, i checked to see if secure boot was enabled and if tis was running the latest kernel in boot dir:
$ mokutil --sb-state SecureBoot enabled (ok) $ uname -a Linux blauwbok 5.10.0-0.bpo.8-amd64 #1 SMP Debian 5.10.46-2~bpo10+1 (2021-07-22) x86_64 GNU/Linux (which was the latest installed) hth, Wim
