ミスをしました。mariadb を 10.0 から 10.2 にアップデートする必要がありました。そのため、次の操作を実行しました。
$ sudo apt-get install mariadb-server
Reading package lists... Done Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install'
to correct these:
The following packages have unmet dependencies:
mariadb-client : Depends: mariadb-client-10.0 (=10.0.33+maria-1~trusty) but 10.0.31-0ubuntu0.16.04.2 is to be installed
mariadb-server : Depends: mariadb-server-10.2 (>= 10.2.7+maria~xenial) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
そして、エラーが発生したため削除しようとしました:

答え1
インストールしたいパッケージには、すでにインストールされているパッケージの同様に新しいバージョンに依存する新しいバージョンがあるようです。これらのパッケージをすべてアップグレードするように指示しない限り、apt はこれを修正する方法を知りません。
sudo apt-get update
sudo apt-get dist-upgrade -f
答え2
試しましたか
sudo service mysql stop
実行する前に:
sudo apt-get --purge remove "mysql*"
ノートパソコンで試してみましたが、うまくいきました。
インストール後に追加されたカスタム設定はそのまま残ることに注意してください。
