    The commands above do work but the KernelCare extension still shows an error message:

    The KernelCare extension has been successfully installed, but some components could not be installed. Please look in the Plesk log (panel.log), and reinstall the components by clicking the button below.

    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

    ERR [extension/kernelcare-plesk] Error message: E: Unable to correct problems, you have held broken packages.

    I use debian 10

    I also followed the instructions below, but it didn't work :
