### 解決したいこと

wsl2でmysqlがインストール出来ません。1つ前の質問のエラーがどうしても解消出来なかったので、brewコマンドを使い、wsl2でmysqlをインストールしてしまいました。参考にした記事はマックのものだったので、ちゃんと実行すべきかよく考えるべきでした(wsl2でbrewを使ってmysqlをインストールするという記事はなかった)。結局途中で出たエラーが解決出来なかったのでアンインストールして正式な方法でインストールし直すことにしました。ですが、ここでエラーが発生してしまいました。

間違って以前のログを消してしまったので、正確にはこのエラー画面ではない（このエラーは現在出ているエラー）のですが、内容は同じで依存関係に関するものでした。このエラーを解決するために、

<https://stackoverflow.com/questions/67564215/problems-installing-mysql-on-
ubuntu-20-04>

この方の記事を参考にしてコマンドを実行しました。この時はコマンドが成功し、一見直ったかのように思い、再度mysqlのインストールを試みるも同じエラーが出てしまいました。参考にしたのはこのサイトです  
<https://docs.microsoft.com/ja-jp/windows/wsl/tutorials/wsl-database>

この時私は恐らくbrewを使ってインストールしたことが原因で依存関係がおかしくなってしまったのだと思い、homebrewをアンインストールしました。その後もう一度インストールを試そうと思ったらまた同じエラーが出てしまい、詰まってしまいました。更に困った事に、先ほどまで使えたコマンドが使えなくなってしまいました。このサイト
