Sounds backwards. You install the repository first, then do an update, and then you do the install. Here are the commands you need to add the repository for CHIRP and install CHIRP in your Ubuntu system:

If you are using Ubuntu linux (or a compatible variant such as Mint) you should install and use the PPA like this:
sudo apt-add-repository ppa:dansmith/chirp-snapshots
sudo apt-get update
sudo apt-get install chirp-daily

After installing the build from the PPA, new updates will be included in your normal system software updates. Also see the Running on Linux page for additional steps required to gain access to your serial port.

E: The repository 
'http://ppa.launchpad.net/dansmith/chirp-snapshots/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 details.

Any suggestions how to overcome this?  The manpage is not really very helpful.

Thanks
