Title:
Secure boot MOK password requested for every kernel update even when
booting in insecure mode
Status in linux package in Ubuntu:
Incomplete
Status in mokutil package in Ubuntu:
Confirmed
Status in update-manager package in Ubuntu:
Confirmed
Bug description:
To reproduce:
- Disable kernel secure boot (booting in insecure mode). System secure boot
still enabled
- Update kernel with update-manager
On every kernel update, a dialog appears asking me to enter a MOK secure boot
password for temporarily disabling secure boot.
See screenshot
When I reboot, the MOK config screen appears, but I can just ignore it and it
boots fine, since secure boot is already disabled in the kernel.
Which makes me wonder why it even needs to ask me to enter a secure boot
password every time I update the kernel.
Expected: only ask for a secure boot password on update if it actually
needs to disable kernel secure boot, and kernel secure boot is not
already disabled.
Note that the output of mokutil --sb-state
SecureBoot enabled
However, kernel secure boot is disabled and the system GRUB bootloader
prints a message "Booting in insecure mode" on startup
