Git error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied

I am having a strange issue that I can't seem to resolve. Here is what happend:

I had some log files in a github repository that I didn't want there. I found this script that removes files completely from git history like so:

#!/bin/bash
set -o errexit

# Author: David Underhill
# Script to permanently delete files/folders from your git repository. To use
# it, cd to your repository's root and then run the script with a list of paths
# you want to delete, e.g., git-delete-history path1 path2

if [ $# -eq 0 ]; then
exit 0are still
fi

# make sure we're at the root of git repo
if [ ! -d .git ]; then
echo "Error: must run this script from the root of a git repository"
exit 1
fi

# remove all paths passed as arguments from the history of the repo
files=$@
git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch $files" HEAD

# remove the temporary history git-filter-branch otherwise leaves behind for a long time
rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune


I, of course, made a backup first and then tried it. It seemed to work fine. I then did a git push -f and was greeted with the following messages:

error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied
error: Cannot update the ref 'refs/remotes/origin/master'.


Everything seems to have pushed fine though, because the files seem to be gone from the GitHub repository, if I try and push again I get the same thing:

error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied
error: Cannot update the ref 'refs/remotes/origin/master'.
Everything up-to-date


EDIT

$ sudo chgrp {user} .git/logs/refs/remotes/origin/master
$ sudo chown {user} .git/logs/refs/remotes/origin/master
$ git push
Everything up-to-date


Thanks!

EDIT

Uh Oh. Problem. I've been working on this project all night and just went to commit my changes:

error: Unable to append to .git/logs/refs/heads/master: Permission denied
fatal: cannot update HEAD ref


So I:

sudo chown {user} .git/logs/refs/heads/master
sudo chgrp {user} .git/logs/refs/heads/master


I try the commit again and I get:

error: Unable to append to .git/logs/HEAD: Permission denied
fatal: cannot update HEAD ref


So I:

sudo chown {user} .git/logs/HEAD
sudo chgrp {user} .git/logs/HEAD


And then I try the commit again:

Hooray. I jump on http://GitHub.com and check out the repository, and my latest commit is no where to be found. ::scratch head:: So I push again:

Everything up-to-date


Umm...it doesn't look like it. I've never had this issue before, could this be a problem with github? or did I mess something up with my git project?

EDIT

Nevermind, I did a simple:

git push origin master


and it pushed fine.

Answer

This looks like you ran git as root locally, thus changing ownership on some of the files tracking the location of the origin branch.

Fix the file ownership, and you should be fine:

# run this from the root of the git working tree
sudo chown -R "${USER:-$(id -un)}" .
