During installation of CUDA 9.2 on my Ubuntu 18.04 desktop machine it reports an error on finding the already installed driver 396.24 I got from PPA. It is trying to install driver 396.26. How can I get rid of the 396.24? I have tried several times using various syntaxes of remove or purge, but I'm obviously not expert enough to get it right.
This is the text of the error message:
