Prevent local branch overwrite - Git pull origin

1. Reset your local master to match the remote repository's master (WARNING: be sure that you don't have any uncommitted changes you want to keep before issuing the following command):

   git reset --hard origin/master
   

2. Fetch all remote branches into your local repository:

   git fetch origin
   

3. Create a new local vsup12 branch from the remote vsup12 branch, and switch to this new local branch:

   git checkout -b vsup12 origin/vsup12
