How to change the remote a branch is tracking?
Using git v1.8.0 or later:
git branch branch_name --set-upstream-to your_new_remote/branch_name
Or you can use the -u switch
git branch branch_name -u your_new_remote/branch_name
Using git v1.7.12 or earlier
git branch --set-upstream branch_name your_new_remote/branch_name
For me the fix was:
git remote set-url origin https://some_url/some_repo
Then:
git push
