You will probably notice it also when trying to push a new branch:

`error: failed to push some refs to ` when using --set-upstream

Indeed, I notice it when trying to push also:

  remote: Resolving deltas: 100% (3/3), completed with 3 local objects.
  remote: fatal error in commit_refs
  To github.com:acme/foo.git
   ! [remote rejected] HEAD -> acme/foo (failure)
  error: failed to push some refs to 'github.com:acme/foo.git'
