Unable to clone All-Users after Gerrit move

About 2 years ago we moved our Gerrit 2.10 site to a new datacenter, copying over the repos as part of the process. This is probably the first time I've tried to access the "All-Users" repo, and I'm seeing the following error:

user@desktop=> git clone ssh://user@gerrit.whoi.edu:29418/All-Users
Cloning into 'All-Users'...
warning: remote HEAD refers to nonexistent ref, unable to checkout.

Other repos aren't experiencing this issue. Is there some way I can troubleshoot and remediate?

Solution

Go to Gerrit > BROWSE > Repositories > All-Users > Branches and check if the HEAD is pointing to "refs/meta/config". Correct if needed.
