Git Push Failure : unable to migrate objects to permanent storage

Question

I have a local repository which I have cloned to another directory on the same machine.

When I do some changes on the clone and commit and then push I get the following error message

I emphasize again that both the cloned repository from which i do the push and the target repository are local and i have Read/Write access to both.

Having encountered this post What does git mean by, "unable to migrate objects to permanent storage"?

I understand i have a permission problem on the remote local repository so i check the files on the local remote directory : .git/objects/pack and indeed one file is readonly

Rafael@MachineID MINGW64 /i/.. path ..  /Main_Model/.git/objects/pack (GIT_DIR!)
$ ls -l
total 1580

but executing chmod -R g+w * on the objects folder as suggested in the first answer comment doesn't help because on the next push the file changes back from rw to r-

i also tried

git config core.sharedRepository true like in this post

but pushing again yields the same error

Answer 1

It appears i had a branch with two stashes in the local remote to which i tried to push.

Deleting the branch with git branch -d

and deleting the stashes with git stash list and git stash drop

Solved the problem
