mariaDBとの愚かな衝突の後でMySQLをインストールできない

MySQLがこの特定のコンピューターに既にインストールされており、MariaDBをインストールしたことは完全に気になりませんでした。同じコンピューターに両方のパッケージがあることの結果にも気づかず、両方のインストールを完全にアンインストールし、両方の依存関係を削除しようとしましたそのうちの。これを行う方法に関するいくつかのチュートリアルをオンラインで探しましたが、まだMySQLの実行に問題があります。以下に、ターミナルウィンドウのスクリーンキャプチャと、私が試した多くの試行済みソリューションのリストがあります。残念ながら、試行した順序を思い出せないほど多く試行したため、MySQLのインストールが機能したいだけなのに、以前のインストールから削除できないものがあり、MySQLのインストールが機能していません。 dpkg：警告を取得します。どんな助けも非常に高く評価されます。 （Ubuntu 20.04）

これは、端末ウィンドウの画面取りです。

更新

破損しているように見えるため、シナプスのLibmysqlclient21を削除しました。シナプスからMySQLを正常にアンインストールし、失敗して再インストールしようとしましたが、mysql-server-8.0のインストールを妨げる実行中のMySQLプロセスが見つからないようです。 （mysql-client、client-8.0、client-core-8.0、serverおよびserver-core-8.0は問題なく再インストールされます）。以下の画面キャプチャが表示されます https://Pastebin.ubuntu.com/p/pJCxYm5K2w/

何が起こったのか理解できません。完全な管理者権限を持つユーザーアカウントを使用してubuntuマシンにリモートアクセスしていましたが、ubuntuのインストール時に作成されたアカウントではなかったので、ようやく直接コンピューターに直接アクセスしてログインしました。元のアカウントと驚いたことに、MySQLのシナプスを介してすべてのMySQLをアンインストールしようとしたときに、警告やエラーがまったく表示されず、安全な側で再生するために次のコマンドを実行しました。

# Sudo apt-get remove --purge mysql-server mysql-client mysql-common -y
# Sudo apt-get autoremove -y
# rm -rf /etc/mysql
# Sudo find / -iname 'mysql*' -exec rm -rf {} \;
# apt --fix-broken install

エラーや警告はまったくなかったので、私はsynapticを起動してmysql-serverを再インストールし（synapticが依存関係を処理しました）、インストールは正しく完了しました。完全な管理権限を持つユーザーアカウントには完全なアクセス権が必要なので、これは私には意味がありませんが、MySQLがインストールされて実行されています

MySQLのようですAPTリポジトリはmysql-commonしたがって、すべてのネイティブ8.0バージョンをアンインストールしますが、ここでは削除せずにアンインストールすることをお勧めします。

Sudo apt remove mysql-client-core-8.0 mysql-server-core-8.0 mysql-server-8.0 mysql-client-core-8.0 mysql-client-8.0

その後、インストールを実行できるはずです。

Sudo apt install --reinstall mysql-community-client-core mysql-community-server-core mysql-common mysql-client mysql-server

最後に、次のコマンドを実行して共有ライブラリを更新できます。

Sudo apt install libmysqlclient21

これにより、既存のバージョンが置き換えられます。
