I’ve noticed that since a couple days I’m getting an error while trying to update my system.
I’m using pop_os 21.10.
sudo apt update E: The repository 'http://ppa.launchpad.net/fenics-packages/fenics/ubuntu impish 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.
It seems like the fenics ubuntu repository got messed up in some way ? (Although I’m not sure what this error actually means).
This is probably not a huge deal since I can still use fenics, but did anyone run into the same issue?
