Undoing a git push

Question

Here s what I did on my supposed-to-be-stable branch       git rebase master First  rewinding head to replay your work on top of it    Fast-forwarded alpha-0 3 0 to master    git status   On branch alpha-0 3 0   Your branch is ahead of  origin alpha-0 3 0  by 53 commits    nothing to commit  working directory clean    git push Fetching remote heads      refs    refs heads    refs tags    refs remotes   refs heads master   up-to-date updating  refs heads alpha-0 3 0    from cc4b63bebb6e6dd04407f8788938244b78c50285   to   83c9191dea88d146400853af5eb7555f252001b0     done  refs heads unstable   up-to-date Updating remote server info   That was all a mistake as I later realized  I d like to undo this entire process  and revert the alpha-0 3 0 branch back to what it was   What should I do

You need to make sure that no other users of this repository are fetching the incorrect changes or trying to build on top of the commits that you want removed because you are about to rewind history.

Then you need to 'force' push the old reference.

git push -f origin last_known_good_commit:branch_name

or in your case

git push -f origin cc4b63bebb6:alpha-0.3.0

You may have receive.denyNonFastForwards set on the remote repository. If this is the case, then you will get an error which includes the phrase [remote rejected].

In this scenario, you will have to delete and recreate the branch.

git push origin :alpha-0.3.0
git push origin cc4b63bebb6:refs/heads/alpha-0.3.0

If this doesn't work - perhaps because you have receive.denyDeletes set, then you have to have direct access to the repository. In the remote repository, you then have to do something like the following plumbing command.

git update-ref refs/heads/alpha-0.3.0 cc4b63bebb6 83c9191dea8

git reset --hard HEAD  git push origin -f  This will remove the last commit from your local device as well as Github

A way to do it without losing the changes you wanted   git reset cc4b63b  git stash git push -f origin alpha-0 3 0 git stash pop   Then you can choose the files you meant to push

I believe that you can also do this   git checkout alpha-0 3 0 git reset --hard cc4b63bebb6 git push origin  alpha-0 3 0   This is very similar to the last method  except you don t have to muck around in the remote repo

Scenario 1  If you want to undo the last commit say 8123b7e04b3  below is the command this worked for me   git push origin  8123b7e04b3   lt branch name gt   Output looks like below  Total 0  delta 0   reused 0  delta 0  To https   testlocation code git    8123b7e   92bc500 8123b7e04b3  - gt  master  forced update   Note  To update the change to your local code  to remove the commit locally as well      git reset --hard origin  lt branchName gt  Message displayed is      HEAD is now at 8a3902a comments entered for commit  Additional info  Scenario 2  In some situation  you may want to revert back what you just undo ed  basically undo the undo  through the previous command  then use the below command  git reset --hard 8123b7e04b3  Output  HEAD is now at cc6206c Comment that was entered for commit  More info here  https   github com blog 2019-how-to-undo-almost-anything-with-git

Another way to do this    create another branch checkout the previous commit on that branch using  git checkout  push the new branch  delete the old branch  amp  push the delete  use git push origin --delete  lt branch name gt   rename the new branch into the old branch push again

The accepted solution  from  charles bailey  is highly dangerous if you are working in a shared repo    As a best practice  all commits pushed to a remote repo that is shared should be considered  immutable   Use  git revert  instead   http   www kernel org pub software scm git docs user-manual html fixing-mistakes  https   git-scm com book be v2 Git-Basics-Undoing-Things

If you want to ignore the last commit that you have just pushed in the remote branch  this will not remove the commit but just ignoring it by moving the git pointer to the commit one earlier  refered by HEAD  or HEAD 1  git push origin  HEAD  branch   But if you have already pushed this commit  and others have pulled the branch  In this case  rewriting your branch s history is undesirable and you should instead revert this commit   git revert  lt SHA-1 gt  git push origin branch

you can use the command reset git reset --soft HEAD 1  then  git reset  lt files gt  git commit --amend  and git push -f

The existing answers are good and correct  however what if you need to undo the push but    You want to keep the commits locally or you want to keep uncommitted changes You don t know how many commits you just pushed   Use this command to revert the change to the ref   git push -f origin refs remotes origin  lt branch gt   1   lt branch gt

git revert is less dangerous than some of the approaches suggested here   prompt gt  git revert 35f6af6f77f116ef922e3d75bc80a4a466f92650  master 71738a9  Revert  Issue  482 - Fixed bug    4 files changed  30 insertions     42 deletions -  prompt gt  git status   On branch master   Your branch is ahead of  origin master  by 1 commit    nothing to commit  working directory clean  prompt gt    Replace 35f6af6f77f116ef922e3d75bc80a4a466f92650 with your own commit
