There is no tracking information for the current branch

Question

I've been using github from a relatively short period, and I've always used the client to perform commits and pulls. I decided to try it from the git bash yesterday, and I successfully created a new repo and committed files.

Today I did changes to the repository from another computer, I've committed the changes and now I'm back home and performed a git pull to update my local version and I get this:

There is no tracking information for the current branch.
    Please specify which branch you want to merge with.
    See git-pull(1) for details

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream develop origin/<branch>

the only contributor to this repo is me and there are no branches (just a master). I'm on windows and I've performed the pull from git bash:

git status:

$ git status
# On branch master
nothing to commit, working directory clean

git branch:

$ git branch
* master

What am I doing wrong?

Answer 1

You could specify what branch you want to pull:

git pull origin master

Or you could set it up so that your local master branch tracks github master branch as an upstream:

git branch --set-upstream-to=origin/master master
git pull

This branch tracking is set up for you automatically when you clone a repository (for the default branch only), but if you add a remote to an existing repository you have to set up the tracking yourself. Thankfully, the advice given by git makes that pretty easy to remember how to do.
