Using GIT I tried to pull down a new remote branch using:

git checkout --track -b my-branch-name origin/my-branch-name

When I did this I got this error message:

fatal: git checkout: updating paths is incompatible with switching branches.
Did you intend to checkout 'origin/my-branch-name' which can not be resolved as commit?

This error message was a tad confusing. The solution in my case was simple though, apparently you can’t switch to a different remote branch if your local master is not up-to-date with the remote origin/master so performing:

git pull

resolved the issue and after this I was able to successfully pull down the remote branch.
