Updating kodi addon repository

It’s been about a year since I’ve upated OSMC. Before I do the upgrade I wanted to get my Metropolis skin updated. To do that I wanted to update my Kodi addon repository. Can’t find where to do that though. I’ve reverted to the OSMC default skin. settings --> Addons --> doesn’t show the repository, and neither do any of the options under addons (my add-ons, recently updated, etc)
I’d like some help getting the repository updated.

Thanks

You would need to update Kodi first.

Thanks. Updated OSMC
Setting --> Add-on browser --> My Add-ons
Eventually got me some where to try updating the repository.
Next I got
“The dependency on xbmc.gui version 5.9 could not be satisfied”
Any ideas on how to resolve that?

Yes, update OSMC.

As I said I did update OSMC (per Sam). Issue persists.
Do I need to start over from scratch?

It looks like Metropolis is still beta for Kodi V18. Metropolis 3.5.0 beta for Kodi 18 (Leia)

Yeah I saw that. I’d still like my repository to be up to date. I’ll go the fresh install route.

What makes you think a repository is not up to date? I don’t think reinstalling is going to change anything from where you currently are.
