问题
I'm trying to commit the changes to my repository but I receive the error below:
git -c diff.mnemonicprefix=false -c core.quotepath=false commit -q -F C:\Users\Contronym\AppData\Local\Temp\bkdweixb.mnu
fatal: cannot lock ref 'HEAD': unable to resolve reference HEAD: Invalid argument
Completed with errors, see above.
I'm using bitbucket and SourceTree.
What's the reason for this commit failing? I was able to commit just fine the last 3 commits over the past week. Then, all of a sudden, I receive this error.
EDIT
I ran git gc and these are the results:
$ git gc
error: bad ref for HEAD
error: bad ref for HEAD
error: inflate: data stream error (unknown compression method)
fatal: loose object 53b65bd9b4fec7f6a7b0b3313c68199a18804327 (stored in .git/objects/53/b65bd9b4fec7f6a7b0b3313c68199a18804327) is corrupt
error: failed to run repack
I checked the directory .git/objects/53/b65bd9b4fec7f6a7b0b3313c68199a18804327 but that doesn't exist. There's two other files there, but b65bd9b4fec7f6a7b0b3313c68199a18804327 doesn't exist.

I had the same problem and the only solution that I found was to navigate to the head like so :
.git/refs/heads/branch_name
And I deleted the head file . Then I went to the console and I used the command :
git reset
Then all the files were unstaged so add them and commit them afterwards.

I had the same problem, this worked for me:
Step 1) - got to .git\logs\refs\heads and open the Document named as YOUR_BRANCH, now copy the ID -numbers in front of your user name and email-
Step 2) - got to .git\refs\heads and open the document named as YOUR_BRANCH delete the line and paste the ID in.
Hope it works for you to

Worked for me, into terminal enter: (branch accordingly to your desires lul)
echo ref: refs/heads/master >.git/HEAD

If you don't mind losing your history, you can delete the .git file and then
git init
This will reinitialize your repository and you can then proceed from there

I had the same issue after calling git commands with the root user inside the working copy. So the owner and owner group of various files under .git/ were changed to "root".
When I switched back to my user account, git could not handle this files anymore, because of the lacking permissions.
It worked again, after resetting the permissions with
sudo chown -R [MY_USER]:[MY_GROUP] .git

When I run into this I just git clone the project into a new file directory and pull the heads folder from located at .git\refs\heads and replace the original heads file in the directory that your having the problem. Then just delete the new clone you created (since it obviously doesn't have the updates your trying to push).

I have the same problem. I just used command:
git reset
Than I removed file /my_project_directory/./git/refs/heads/master and than I can use command
git reset --hard <my_hash_of_last_commit_on_remote_branch>
