Thanks Peff, I've checked the permission of .git/objects/16, it's
created by another user and thus I have no permission to remove it.

In fact, this is coming from a previous bad practice on setting up a
collaboration repository on a SSH server, here is what I've done so
far:
[...]
7. Then the user "git" has changed mode for all the files under .git
to writable.

8. This time, user "johnny" can push successfully.

If you are going to have multiple users sharing a repository, generally
they should be in the same group and the core.sharedrepository config
option should be set (see "git help config", or the "shared" option to
git-init).

I've never used that personally, though. I have always just used POSIX
ACLs, with a default ACL on each directory giving access to everyone.
E.g. (off the top of my head):

  for user in user1 user2 user3; do
    setfacl -R -m u:$user:rwX -m d:u:$user:rwX /path/to/repo
  done
