I've installed ksuperkey via cloning from git and compiling with make. Now when I run "apt update" it has an error:
username@osboxes:~$ sudo apt update

I don't care to update this ksuperkey item and want to just "apt update" everything else. I found a similar posting "What can I do if a repository/PPA does not have a Release file?" that I got to through Updating from such a repository can't be done securely [duplicate]. And I tried to ppa-purge the mahnik/ksuperkey, but that hasn't worked:
username@osboxes:~$ sudo ppa-purge ppa:mehanik/ksuperkey

In summary, How can I get rid of this "mahanik/ksuperkey doesn't have a Release file, Can't update from securely" error to ensure my "apt update" works?
