git fetch --all and git pull -all will only track the remote branches and track local branches that track remote branches respectively.

But it is not sufficient to track all remote branches

For tracking all remote branches run this command

   for remote in `git branch -r`; do git branch --track ${remote#origin/} $remote; done

Run this command only if there are remote branches on the server which are untracked by your local branches.

Then after this command run

git fetch --all

git pull --all

Thus, you can fetch all git branches.

On a side note: some will suggest you with

   git branch -r | grep -v '->' | while read remote; do git branch --track "${remote#origin/}" "$remote"; done

"refname 'origin/branchname' is ambiguous whenever you referred to it.

Note : For git fetch all, just need to run git fetch, which will retrieve all branches and updates, and after that, run git checkout which will create a local copy of the branch because all branches are already loaded in your system.
