Can't purge if apt-get update fails (18.04)

[Dima]

I want to purge buggy ppa that makes apt-get update to report error, but I can't because apt-get update reports error. It's a circle.

I can remember a good times when ppa-purge didn't call for apt-get update at all (or that was "add-apt-repository", don't remember...). And everything was ok. I think it's just a wasting of time in the most cases. If I wish to "apt-get update" I'd like to do it manually. But ppa-purge does't have a way to let me avoid it.

The buggy ppa is ppa:swatchbooker/ppa. It doesn't have a Release file for bionic for now so "apt-get update" passes the error to ppa-purge and that's it. One can try to add this repo and then ppa-purge it on Ubuntu bionic.

And I guess the solution is in deleting "exit 1" on line 120 of bionic ppa-purge script
