Git: insufficient permission for adding an object to repository database

Question

I have git error: "insufficient permission for adding an object to repository database" every time I make "git push origin master".
I tried solution described here: http://parizek.com/2011/05/git-insufficient-permission-for-adding-an-object-to-repository-database-objects/ but it works only until next time...
Is there some permanent solution?

Answer 1

As mentioned in "Error pushing to GitHub - insufficient permission for adding an object to repository database", you need, in addition of the git config setting, to:

• first set the umask for all your repos: umask 002 (so on your server side)
• then set the git group to rw as mentioned in your solution, still on the server side.

Answer 2

That usually happens when someone commited to git while booing root. The .git/* files created in that process are protected from external change.

chmod -R 777 .git 

is a fast fix.
