fatal: A branch named ‘xxxxxxxxxxxx’ already exists when git_checkout

Error-

It looks like you are trying to checkout into a branch with -b parameter, which will force to create new branch and checkout.

For an example,

git checkout -b my_branch

If your command is similar to above one, and you have already created the branch my_branch, you will probably get this error.

Solution-

Don’t specify -b parameter when you need to checkout an existing branch

git checkout my_branch
