Hey,

I'm using a gitosis server. Suddenly I'm not able to push to the remote server. Everyone else is able to push to the same server. Btw I can't push to *any repo* on the server. This is the error I get:

Counting objects: 5, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (3/3), done.
Writing objects: 100% (3/3), 353 bytes | 0 bytes/s, done.
Total 3 (delta 1), reused 0 (delta 0)
error: unpack failed: unpack-objects abnormal exit
To git://git.srv.net/code-repo.git
 ! [remote rejected] master -> master (n/a (unpacker error))
error: failed to push some refs to 'git://git.srv.net/code-repo.git'

I Tried git fsck too:c

git fsck --full Checking object directories: 100% (256/256), done. Checking objects: 100% (2844/2844), done.

Can something be wrong with my git installation? git --version git version 1.8.3.2

-Thanks & Regards,

You are trying to push over the "git://" protocol. That isn't enabled by default (because it has no authentication at all). Did you enable it? If so, does the user running git-daemon have permission to write to the repository?

The server notes that unpack-objects fails, but in older git versions the stderr of unpack-objects does not get sent to the client. If your git-daemon process is logging somewhere, you might check that log for more details.

Since v1.7.12.3, that output is sent over the sideband channel to the client. So another option is to upgrade the version of git on the server.

That's your client version. The server version is older than that (in v1.7.12.3, the unpacker error message also dropped the "n/a" bit, so the output above comes from a server older than that).

Thanks a lot for replying!

That exactly was the problem. We've configured gitosis to allow access over 'ssh://' (Read / Write) while 'git://' access was limited (Read only). Changing the configuration worked out just fine.

-Thanks & Regards, Sitesh
