How do you install 'peer guardian linux' in Ubuntu 18.04?
In my previous version of Ubuntu 16.04 LTS this worked:
sudo add-apt-repository ppa:jre-phoenix/ppa
sudo apt-get install pgld pglcmd pglgui
In 18.04 LTS I get following message after trying to install pgl:
E: The repository 'http://ppa.launchpad.net/jre-phoenix/ppa/ubuntu bionic 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.
Can someone help me, please?!
