I installed some PPAs. Now, when I run apt update
some of them seem to be gone.
Err:22 http://ppa.launchpad.net/webupd8team/atom/ubuntu cosmic Release
404 Not Found [IP: 91.189.95.83 80]
Now, I would like to do the following:
sudo ppa-purge http://ppa.launchpad.net/webupd8team/atom/ubuntu
But this does not work.
I assume ppa-purge only accepts input in the form of ppa:somerepo/path
Is there a way to remove a PPA by its http... URL?
The PPA you mentioned does not contain files for cosmic (18.10) distro.
So you can simply remove it from sources.list with:
and then check that
sudo apt update
is successful.
