Ubuntu did a partial-upgrade to Ubuntu Focal Fossa (development branch)
The following CQRlog applications were installed.
CQRLOG - 2.4.0-3
CQRLOG-DATA - 2.4.0-3
Now my CQRlog does not open, believe it to be unstable.
I cannot remove the applications - because says installation must be reinstalled.
When attempt to reinstall - does not complete because of error.
When attempting to update ppa from: "http://ppa.launchpad.net/ok2cqr/ppa/ubuntu focal main"
Receive the following error.
"E: The repository 'http://ppa.launchpad.net/ok2cqr/ppa/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default."
How can I remove, or repair my CQRlog installation?
