git - Failed to lock refs/heads/master

Question

I am relatively new to git and am facing this problem. The git push command shows the error below. I will explain to you from the beginning what I had been trying to do. I created a submodule, committed, and pushed it. The push throws the error below.

Salman@PC_HOME ~/git/breakit-web-app (master)
$ git push origin master
error: refs/heads/master does not point to a valid object!

To ssh://git@bitbucket.org/majuri/breakit-web-app.git
 ! [remote rejected] master -> master (failed to lock)
error: failed to push some refs to 'ssh://git@bitbucket.org/majuri/breakit-web-app.git'

Here is a screenshot:

After that, I tried some solutions, but none of them worked. I will also explain briefly what I have been trying.

1: From the bitbucket repo, I noticed there are some dangling commits (the red arrow in picture 2), so I gave the following commands to solve that git gc and git prune.

2: I also tried commands like git revert HEAD and git push origin HEAD --force, but none seem to work.

Other details:

$ git rev-parse --symbolic-full-name master
refs/heads/master

$ git rev-parse master
0da090c5cbde10ff19602a2722ae05231c30dff5

$ git show-ref master
0da090c5cbde10ff19602a2722ae05231c30dff5 refs/heads/master

Thank you

You have to update the HEAD known by git. It will be transparent for you.

1. Go to master branch

   git checkout master
   

2. Get updates from the remote to your local repository

   git fetch
   

3. Update your local repository using rebase instead of merge. See there difference between git pull and git rebase

   git rebase origin/master
   

4. Push your master branch

   git push origin master:master
