Hi, I cannot install a web application on ubuntu 20.04 or 18.04. It is getting an error.
404 Not Found [IP: 126.96.36.199 80] Reading package lists… Done E: The repository ‘http://ppa.launchpad.net/brightbox/ruby-ng/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…
