14.04 LTSから16.04 LTSにアップグレードすると多くの問題が発生し、MySqlがインストールされなくなりました

この質問には多くの繰り返しがあったことがわかります（ここでは、ランチパッド、スーパーユーザーなど）。私はここですべてのソリューションと提案を試しました 16.04アップグレードはmysql-serverを壊しました 、ここ https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/ 156916 、ここ https://bugs.mysql.com/bug.php?id=72722 しかし、何も助けていない。

以下は、インストール失敗後のSudo dpkg --configure -aの出力です。

誰でも助けてくれますか？私はこれで終わりであり、新規インストールを行いたくありません。仕事用のソフトウェアをインストールできるように、このインストールを完了する必要があります。

OK、私はそれを理解したように見えます。これで問題が解決しました。

Sudo dpkg -P --force depends mysql-server mysql-server-5.7 mysql-common mysql-server-core-5.7 php5-mysql mysql-client-5.7 mysql-client-core-5.7
