Linux Mint 18.3（Ubuntu Xenialベース）。
ここで他の質問を見てきましたが、まだパッケージリスト、特にMariaDBのクリーンアップをどこで始めるべきかわかりません。これらのリストの管理と考慮事項の詳細を読むためのリンクがあることをお勧めします。
以下の出力で特に知りたいことが一つあります。 MariaDB（MySQL）のインストール時にどうすればよいですか？
mysqlとmysqldのバージョンを見つけようとすると、次のメッセージが表示されます。
mikeM17A ~ $ mysql --version
mysql Ver 15.1 Distrib 10.2.16-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
mike@M17A ~ $ mysqld --version
mysqld Ver 10.2.16-MariaDB-10.2.16+maria~xenial for debian-linux-gnu on x86_64 (mariadb.org binary distribution)
/etc/apt/sources.list.d/には、このMySQLの問題に関連しているように見える2つのファイル（MariaDB101.listとMariaDB102.list）があります。たとえば、後者には1行だけが含まれます。
deb https://mirrors.evowise.com/mariadb/repo/10.2/ubuntu serena main
これを取り除くつもりはありますか？その後、Synaptic（10.2.27）で利用可能なMariaDBをインストールする必要がありますか？問題は、「mariadb」という単語を含むパッケージが数十個あることです。どのパッケージをインストールするのかわかりません。
これにより、既存のMariaDBインストールを何とか「上書きする」ことができますか？
この結果について他のコメントがあれば、sudo apt-get update大変感謝いたします。
mike@M17A ~ $ sudo apt-get update
