補足情報（FW/ツールのバージョンなど）

zyboz7-20上でubuntu18.04が動いており、TeraTermにてwindows10のPCとシリアル通信を行っています。
勉強を始めたばかりで至らない点も多いとは思いますがよろしくお願いします。

これと現象が同じ？ https://ubuntu.forumming.com/question/2978/trouble-with-apt-get-update-and-default-repositories リポジトリサイトを国内のミラーサーバーに変更すると良かったりして。

シリアル通信で、というのが気になります。ubuntuサーバーはインターネット繋がってますか？

DNSサーバーのIPアドレスを登録できてないんじゃないの？

上記の問題はtimezoneの設定を行うことで解決しましたが、投稿時のエラーが再度でてしまいます。

binary-armhf/Packageが、sources.list内で指定されている archive.ubuntu.com/ubuntuではなく、ports.ubuntu.com/ubuntu内に存在しているので、 sources.listを書き直すとエラーは発生しなくなった。
