I am using Ubuntu 22.10 on a Digital Ocean image. I try to run this command:
sudo apt-add-repository -y ppa:brightbox/ruby-ng
but I get these specific error messages in output;
Err:3 http://old-releases.ubuntu.com/ubuntu kinetic-security Release
404 Not Found [IP: 185.125.190.37 80]
Err:8 https://ppa.launchpadcontent.net/brightbox/ruby-ng/ubuntu kinetic Release
