git checkout - Git, How to reset origin/master to a commit?

Question

I reset my local master to a commit by this command:

git reset --hard e3f1e37

when I enter $ git status command, terminal says:

# On branch master
# Your branch is behind 'origin/master' by 7 commits, and can be fast-forwarded.

#   (use "git pull" to update your local branch)
#
nothing to commit, working directory clean

Since I want to reset origin/header as well, I checkout to origin/master:

$ git checkout origin/master
Note: checking out 'origin/master'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

HEAD is now at 2aef1de... master problem fixed for master. its okay now.

and reset the header by this command:

$ git reset --hard e3f1e37
HEAD is now at e3f1e37 development version code incremented for new build.

Then I tried to add commit to origin/header that I was not successful.

$ git commit -m "Reverting to the state of the project at e3f1e37"
# HEAD detached from origin/master
nothing to commit, working directory clean

Finally, I checkout to my local master.

$ git checkout master
Switched to branch 'master'
Your branch is behind 'origin/master' by 7 commits, and can be fast-forwarded.
  (use "git pull" to update your local branch)

Since, I reset the head of origin/master I expect local and origin should be in same direction but as you see, git is saying that my local/master is behind origin/master by 7 commits.

How can I fix this issue? The things that I'm looking for is Head of local/master and origin/master point to same commit. Following image shows what I did. Thanks.

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master
