WSLのLinux(Ubuntu)にバージョン指定してMySQLをインストールするコマンドがわからない

現在Railsの環境構築をしている所です。

WSLのUbuntu 18.04でMySQL 5.7をセットアップしたいのですが、

$ sudo apt install mysql-server mysql-client

を実行してしまうと最新のMySQL8.0がインストールされてしまうみたいです。既存のプロジェクトが5.7なので5．7を使いたいのですがバージョン指定するコマンドの記述方法がわかりません。

調べたのですがでてきませんでした。

どなたかご教授いただければ幸いです。。

よろしくお願い致します。

##試したこと

sudo apt install -v mysql-server 5.7 mysql-client
sudo apt-get install mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7

調べて↑を入力してみましたがダメでした。

二つ目の実行結果は以下のようなエラーが出ました。
