List-ppa

Fetch and list all available ppas from https://launchpad.net/ubuntu/+ppas?name_filter=

Available with pip/pipx on: https://pypi.org/project/list-ppa/
Very simple script, but it does check whether the ppa is available for your specific version of Ubuntu.
It does take a while for it to look up all the possible ppas, therefor it is not adviced to run it constantly but rather to keep the output of the script in a file which you can regenerate every so often. Running it without any argument will trigger a prompt that asks you wheter you want to save it to a file or not.

Checking repo availability can be disabled with --not-check-available
