When you are dealing with a local git repository which has multiple remotes defined (i.e. has multiple remote repositories possibly carrying the same branches, such as multiple forks), then the right way to checkout a working branch from one of them is to use the below syntax:
git checkout -b master origin/master
Where origin is the name of the remote.
You can also delete a local branch before switching to another repository’s copy of it:
git checkout origin/master git branch -D master git checkout -b master origin/master
