You might check that the kelebek repository was fully added using software & Updates app and if it was, run
sudo apt update && sudo apt full-upgrade

I do not personally know of a method.
This is why I say that upgrading your computer or your graphics is one of the few remaining options for you.
oh, I understand, thank you very much
