git push で「insufficient permission for adding an object to repository database」のerrorが出た場合の対象方法

リモートサーバにpushできない事態が発生したのでその対象方法を以下にメモしておく

以下のようなエラーが発生

$ git push
Counting objects: 7, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (4/4), done.
Writing objects: 100% (4/4), 392 bytes, done.
Total 4 (delta 3), reused 0 (delta 0)
error: insufficient permission for adding an object to repository database ./objects

fatal: failed to write object
error: unpack failed: unpack-objects abnormal exit
To git@*********:document.git
 ! [remote rejected] master -> master (n/a (unpacker error))
error: failed to push some refs to 'git@*******:document.git'

1. git サーバにログイン、対象のリポジトリに移動、以下のコマンドを実行

    $ chmod -R g+ws *
    $ chgrp -R git *
    $ git repo-config core.sharedRepository true
   

2. 開発マシンからもう一度pushする

    $ git push
    Counting objects: 7, done.
    Delta compression using up to 2 threads.
    Compressing objects: 100% (4/4), done.
    Writing objects: 100% (4/4), 392 bytes, done.
    Total 4 (delta 3), reused 0 (delta 0)
    To git@*********:document.git
       c27c63c..b9ee86b  master -> master
