I am working on basing a new OS off of Ubuntu 18.04 Bionic, and in order to properly have the OS be recognized as a new distribution, I had to change /etc/lsb-release. In order to have it use PPAs, I had to add a file to /usr/share/python-apt/templates. This got it to add the PPAs, but, it defaults to Eoan repositories when I attempt to add them.
You can see what I have in my GitHub repository here.
Is there some other file I need to add? Am I formatting the *.info file wrong? Is it something else?
Thanks in advance!
