Hi,

I've installed KernelCare from the Plesk Onyx 17 Extension Manager and I instantly got mails and installation errors saying:
Unknown Kernel (Ubuntu 3.13.0-042stab120.20)


I then uninstalled the KernelCare plugin with the Plesk Extension Manager and even tho it's removed from the Extension Manager, I keep getting the errors and about 60 error emails each hour.

When I run apt-get remove kernelcare I get this output:

[email protected]:~# apt-get remove kernelcare

Thanks!

I solved it by removing the file
kcare
in
/ect/init.d/
, then rebooted the machine and running
dpkg --force-all --purge kernelcare


This resulted in the successful removal of KernelCare:

kernelcare cannot be used with proxmox lxc. There should be a check for lxc vm's, otherwise you run into errors..

It can be, but only on the host system, not inside containers

Yeah I know, in my opinion there should be a message for something like that, e.g. "kernelcare cannot be used inside lxc containers."

ATM you just get a writable error message
