I am using GIT for versioning for me and my co-worker, and since the beginning I am running into an error that randomly effects either me or my co-worker.
We have two different users that push/pull to our Git-Server. Both are members of the same group gitusers.
From time to time (not all the time), if one of us pushes his changes to the server, the other gets an: ERROR: failed to push some ref to '' Changes were of course pulled before.
If found out that the permission for .git/refs/HEADS/[PROJECT_NAME] changed from rw-rw-r to rw-r-r so readonly for other group members. Owner is the last user who successfully pushed to the server.
I don't understand why. Especially because it does not happen all the time.
Can someone offer any advice?
