Hi,
when I use the command: git push
I get these two errors:
...
error: Unable to append to logs/HEAD: Permission denied
...
error: failed to push some refs to 'ssh://remote server'

However, the changes are pushed in the remote repository.

Does somebody have any ideas?
Thanx,

Is this a shared repo by any chance (i.e. accessed by different user
ids, not just by different people using the same git-account)?

yes!
This is about a shared repository that is allowed to be accessed by its
owner and group.
The group consists of some machine users.
Users have different accounts and modify the git-repository by own account.

Then you might want to read up on core.sharedRepository in git config's
man page and set it according to your situation (all users in the same
group, e.g.). Also, you'll have to fix-up permissions manually at least
on logs/HEAD (and probably others).

Cheers,
Michael

```

after configuring git and setting core.sharedRepository to true at server
side, I do not get the first error any more. But the second one still
appears on the screen after every push.
error: failed to push some refs to 'ssh://remote server'

That means that in addition to the 1st part, you'll also have to follow
the 2nd part of my advice ;)

Thank you, Michael!
I do not understand what you exactly mean with "Also, you'll have to fix-up
permissions manually at least
on logs/HEAD (and probably others)"
If you mean that I have to change the permission of logs/HEAD to read, write
for the group, it is already done.
All files and directories in the repository are accessible for the group.

I meant all files & dirs under ${repo}.git should be owned by the group
and +rw for the group. ["All" is actually overkill but sufficient.]

Hmm. If really all files and dirs (!) are group writeable I'm puzzled.
What is the complete report and error message (besides failed to push)?

A push can also fail due to non fast-forward, of course.

The push is succeed but I get this error every time. This is de complete
message:

user@server's password:

As you can see the push is done but I get the error.

Is the repo on the server side in a good state? I.e., if you do

git status
git fsck
git show-ref

in the server side repo, is there something strange?
Another thing worth trying would be to

git clone --shared --mirror LRSystems LRSystems-new

and check whether pushing to that freshly set-up repo works.

Thanks Michael!
I solved the problem by making a new repository on the server and cloning to
the local computer.
