git fetch --all
You can fetch all branches from all remotes like this:
git fetch --all
git branch -rgit branch -a #all local and remote branches are listed
git branch -r #remote branches are listed
git branch #only local branches are listedgit branch -r
# If this doesn't work for you, try
git ls-remote --heads <remote-name>
