git checkout tag, git pull fails in branch

Question

I have cloned a git repository and then checked out a tag:

# git checkout 2.4.33 -b my_branch

This is OK, but when I try to run git pull<

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.

--set-upstream is deprecated in git 1.9.x, apparently. Going forward you'd want to use something like

git branch -u origin/master

assuming you've checked out master already. If not, git branch -u origin/master master will work
