How do I install 5.1.7? The add on is not updating on its own. I tried installing manually but says add on does not have correct structure.

Via my repo it's compatible with Gotham, but be aware of some addons won't work properly, because most addons expect version 4.X of YouTube with Gotham. So to avoid more complex problems...you should really consider to upgrade at least to Helix. This won't get better

Check if you've disabled the auto update. I'm pretty sure that the update should go for 5.1.8 via my repo.
