[Dagged]

I have an issue with upgrading NSX-T 3.2 to NSX 4.1, here's the error message:

Pre-upgrade checks failed for MP: Repository sync is not complete onhostname1. Please wait for the repository sync to complete, or resolve errors if repository sync has failed

having look at the logs:

I have seen this on VCF 4.5.0, Had to restart the Service on GUI.

On node which is reporting, follow this steps.

Appliances ->VIEW DETAILS -> REPO_SYNC -> Resolve.

Faced the same problem while upgrading NSX-T 3.2.1 -> 3.2.3.

Try System -> Appliances-> View Details (on failed appliance)

The OPERATIONAL STATUS of REPO_SYNC shows FAILED (not SUCCESS) and there should be a resolve button...
