Comment # 5 on bug 1191804 from Ondrej Holecek

Just to clarify for others, this seems not to be related to the SB as I have
exactly the same error but with SB enabled:

> (1/2) Installing: kernel-default-5.14.11-1.2.x86_64 [.............error]
> Installation of kernel-default-5.14.11-1.2.x86_64 failed:
> Error: Subprocess failed. Error: RPM failed: SecureBoot enabled

This seems to be related to MicroOS.
