Getting a message telling me there is an update available for YouTube. If I download the update I get a message telling me it's updated, but there is still always an available update.
I am guessing this is an issue with the addon being on multiple repos. Can you please remove YouTube from your repo so it doesn't conflict with the official repo?
I could just remove your repo, but YouTube is not the only addon of yours I use, so I would like to avoid it.

It has nothing to do with 2 Repos. Gotham and KODI have some issues to update from a beta to a final. I tested it with KODI and Gotham and some times if not most of the time the update from beta to final loops.
Simple solution in this case: Uninstall YouTube and install again and everything is fine.

I think about another way to test new versions of YouTube before PR the final update.

Really strange. It should just "work".
can you test it again to be sure and create a trac ticket.
perhaps cc Montellese as he did the last changes in the update logic.
