bash：/etc/bash.bashrc：端末を開くたびにアクセスが拒否される

Ubuntu 13.10で新しいターミナルを開くと、ターミナルに次の出力が表示されることがあります。

bash: /etc/bash.bashrc: Permission denied

ただし、権限は問題ないはずです。

>ls -l /etc/bash.bashrc
-rwxr-xr-x 1 root root 2177 Mär 30  2013 /etc/bash.bashrc*

何が問題ですか？どうすれば修正できますか？ファイルの目的は何ですか/etc/bash.bashrcそして正確にどこで呼び出されますか？

試してください：chmod 0755 /etcをルートとして。/etcディレクトリの権限が間違っているという問題が発生した可能性があります。また、bash.bashrcファイルの権限を元の権限に戻しますchmod 644 /etc/bash.bashrc。
