I understand that
E: The repositoryhttp://ppa.launchpad.net/cpug-devs/ppa/ubuntu bionic Release' does not have a Release file.
is the error. So how do I fix it?
[Edit]
I have found the problem is solved(I just removed the problem causing repo ).
http://ppa.launchpad.net/cpug-devs/ppa/ubuntu/dists/in a browser and looked at what versions of Ubuntu are supported - bionic or 18.04 isn't there which is why you are getting an error. I don't know why you added it, but you need to remove it (or comment it out) or find another source for whatever you wanted from there as 18.04/bionic isn't supported by that ppa. We can't provide a solution, as we don't know why you added it to your sources. – guiverc Jun 17 '18 at 02:21
