Main Kodi Repository is Missing

I have a fresh 20.2.0 Kodi install and the main Kodi repo is missing. This is (mostly) preventing me from installing addons due to missing dependencies. I’ve kind of gotten around that by manually installing dependencies from this location, but it’s kind of a pain.

I’m talking about common packages like “plugin.googledrive” and “script.module.*”, etc…

How can I manually install the Kodi Addon Repository, and any other basic repos that should have been installed by default?
