The commands above do work but the KernelCare extension still shows an error message:
When clicking the "Reinstall components" it will generate some files in the /opt/psa/var/modules/kernelcare-plesk folder :

But then disappears leaving the file "packagemustberemoved":
I've done the whole procedure several times but still stuck here.
FYI my Plesk is up to date.
I have the same problem and if I look in the panel.log I see the following line
I use debian 10
I also followed the instructions below, but it didn't work :

Same behavior as above also on latest Debian 11.
The Resolution for KernelCare helped me, thank you very much!
