Do you have a custom kernel?

matteocorti commented 3 years ago

Can you please post the output of

rpm -qa | grep ^kernel'

?

MAngel666 commented 3 years ago 
rpm -qa | grep ^kernel
kernel-tools-libs-4.18.0-305.25.1.el8_4.aarch64
kernel-tools-4.18.0-305.25.1.el8_4.aarch64
kernel-headers-4.18.0-305.25.1.el8_4.aarch64

I dont use a custom kernel but the RPi kernels are not installed as rpm. It seems to be a specialty of the CentOS version fpr RPi4. The "standard" C8 kernel doesnt support RPi4.

Ok then I propose to skip the kernel checks if the kernel is not installed as an RPM. The plugin would then only check the RPMs...

I just committed a new version but I don't have an RPi system to test. Can you please check?

btw: it would be nice if you add the new build dependency to spec file: perl-Module-Install

Seems to work. I'll add the missing newline in the verbose message and take a look at the dependency
