After doing a checkout of the remote branch releases/rel_5.4.1 using the Git GUI, I\'m seeing this unexpected error message when I try to push:
releases/rel_5.4.1
push
This error can be fixed for once and all, with:
git branch releases/rel_5.4.1 -u origin/releases/rel_5.4.1
It changes the upstream of the branch, to match the correct remote (again).
