I have tried several installs of wine Ubuntu 20.04 and they fail at the same point with the following:
$ sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ focal main'

Reading package lists... Done
E: The repository 'http://ppa.launchpad.net/fingerprint/fprint/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.
N: See apt-secure(8) manpage for repository creation and user configuration
apt-secure(8) says something about accepting ppa's with no Release files but the specific steps are not specified. Any suggestions as to how to proceed will be appreciated.
