Git Push Error

Question header Git Push Error: insufficient permission for adding an object to repository database.
Original question
When I try to push to a shared git remote, I get the following error: insufficient permission for adding an object to repository database
Then I read about a fix here: Fix This worked for the next push, since all of the files were of the correct group, but the next time someone pushed up a change it made a new item in the objects folder that had their default group as the group. The only thing I can think of is to change all of the developer's default group for items they check in, but that seems like a hack. Any ideas? Thanks.

Working Answer
Use the following command, works like magic:

$ sudo chown -R "${USER:-$(id -un)}" .

Type the command exactly as it is (with extra spaces and one dot at the end, but without the starting dollar sign = prompt)
