解決法

  • 先人の知恵によりコマンドsudo apt-get updateを実行した際のパッケージリストが悪さをしていることが分かった。
  • パッケージリストを先に削除してあげることで正常にコマンドsudo apt-get updateが実行できた。
  1. 下記コマンドを実行してパッケージリストを削除する。
  $ sudo rm -rf /var/lib/apt/lists/*
  1. 今一度、コマンドsudo apt-get updateを実行する。
  $ sudo apt-get update
  1. 下記の様に出力されればコマンドsudo apt-get updateが正常に実行できている。
