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

I had the same problem and fixed it with this command:

$ git push -u origin master

From the help file the -u basically sets the default for pulls:

-u, --set-upstream`

  For every branch that is up to date or successfully pushed, add 
  upstream (tracking) reference, used by argument-less git-pull(1) and
  other commands. For more information, see branch..merge in 
  git-config(1).
