Good morning everybody,
my issue is by-somehow similar to #396...
when I try to update my Packages Update index: sudo apt-get update
Ign:20 http://ppa.launchpad.net/peek-developers/stable/ubuntu groovy InRelease
Err:22 http://ppa.launchpad.net/peek-developers/stable/ubuntu groovy Release
404 Not Found [IP: 91.189.95.83 80]
The package in the PPA has not yet been built for groovy. But Peek 1.5.1 is also available in Ubuntu's universe repository, so there is not really a need for it.
Once a new version gets released it will be made available in the PPA
Thank you ! that answers my question
maybe update the README for Ubuntu 20.10, since the PPA is not required for the current stable?
