【Capistrano】git stdout: error: cannot open FETCH_HEAD: 許可がありません

Question

##状況

Railsアプリをec2 + nginx + unicorn + capistranoでの自動デプロイに挑戦しているのですが、設定をし終えてbundle exec cap production deployをするとGit周りのエラーが起こってしまいます。

##エラー内容

$ bundle exec cap production deploy
省略
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as Stelle@3.112.153.67: git exit status: 1
git stdout: error: cannot open FETCH_HEAD: 許可がありません
git stderr: Nothing written

これまでの流れとしては、サーバー上で~から.gitconfigを編集し、その後は以下のとおりです。

[Stelle@ip- ~]$ chmod 700 .ssh

[Stelle@ip- ~]$ cd .ssh

[Stelle@ip- .ssh]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
省略

[Stelle@ip- .ssh]$ vim config
Host github
  Hostname github.com
  User git
  IdentityFile ~/.ssh/xxx_key_rsa
これで保存

[Stelle@ip- .ssh]$ cat xxx_key_rsa.pub
Githubにssh接続

[Stelle@ip- .ssh]$ chmod 600 config

[Stelle@ip- .ssh]$ ssh -T github
Hi sakanafuto! You've successfully authenticated, but GitHub does not provide shell access.

[Stelle@ip- .ssh]$ cd

[Stelle@ip- ~]$ ssh-add ~/.ssh/xxx_key_rsa
Could not open a connection to your authentication agent.

[Stelle@ip- ~]$  eval "$(ssh-agent)"
Agent pid 27483

[Stelle@ip- ~]$ ssh-add ~/.ssh/xxx_key_rsa
Identity added: /home/Stelle/.ssh/xxx_key_rsa (/home/Stelle/.ssh/xxx_key_rsa)

この後にローカルで先程のようにデプロイするとエラーに成ってしまいます。

設定ファイル「deploy.rb」と「production.rb」は質問文に掲載しておきましょう
gitの設定がどちらかには書かれているはずで、そこに手掛かりがありそうです

[sakanafuto]

コードをいくつか追加しました！

Answer 1

サーバ側でsudo chown -R () .で出来ました。
