あなたのapt policy Perl perl-base出力、および 指摘 by jordanm 、システムにはDebian9バージョンではなくBusterバージョンのPerlがあります。したがって、システムは実際にはDebian 9.5の「フレッシュインストール」ではありません。 PerlはDebianセットアップの非常に重要なコンポーネントであるため、Busterバージョンにアップグレードされた他の多くのパッケージが存在する可能性があります。

このPerlの不一致が、MySQLパッケージをインストールできない理由です。

これは最近のインストールであり、それにあまり投資していません。したがって、ヨルダンの 再インストールの推奨 は、おそらくこの場合の最良の解決策です。 Debian 9とBusterはかなり分岐しているため、特にPerlをアップグレードしたため、ロールバックはかなり複雑になる可能性があります。 mcを削除するだけでは確かに十分ではありません。

将来的には、安定版とテスト版を混在させないでください。パッケージを使用できないバグに遭遇した場合は、バグを報告してください（reportbug mc）;十分に深刻な場合は、安定した更新の対象となる可能性があります。バックポートを要求することもできます。これにより、Debian 9用に再構築されたmcの現在のバスターバージョンが取得されます。
