既出の質問ならすみません。
はじめまして。Ubuntu 18.10 LTS を使用しています
・現象
作業中に、/opt/内のどこかのディレクトリのパーミッションを chmod コマンドで変更したところ、フリーズした。その後強制的に再起動したところ ubuntu のロゴがでたあと、エラーが表示されて起動しなくなった。
以下がその画面に表示されているログ(?)

・試したこと
Advanced Options から直前のkernelから起動を試した。
その際も以下のログがでて起動しなかった。

Recovery mode からfsckやclean を実行してみたが同様に起動しなかった。
初めてUbuntuが起動しなり、どこから手をつけていいのか分からなかったので、とりあえずログを貼らせてもらいました。
こういった場合にはどのように解決すればよいのか、ご教示ください。
よろしくお願い致します。
