Hey, I'm using Linux Ubuntu 22.04. On my old Laptop with Ubuntu 18.04 I was already using UPM, but now I have problems to install it on my new Laptop. When adding the repositories there appears an error message, that the link https://ppa.launchpadcontent.net/adriansmith/upm/ubuntu does not contain a release file (404 Not found). In the Attachment you find the complete copy of the terminal - but its in German. Do you have any ideas? Thanks a lot!
