2つのUbuntuサーバー（20.04.5）があります。 1つはカーネルバージョン5.4.0-137-genericで、もう1つはカーネルバージョン5.15.0-66-genericです。私は彼らが同じカーネルバージョン（5.15.0-66-generic）を持つことを望みます。ただしsudo apt-get install linux-image-5.15.0-66-generic、コマンドを実行すると、次のエラーメッセージが表示されます。

利用可能なカーネルバージョンのリストを確認してみると、私が探しているカーネルバージョンがリストにありません。

なぜこれが起こるのか、どのように解決するのか知りたいです。
答え1
linux-image-5.15.0-66-genericJammy（20.04ではなく22.04）に提案されたアップデートですが、アップデートリポジトリにアップグレードされませんでした。linux-image-5.15.0-67-generic。
両方のサーバーが20.04を実行している場合は、5.4カーネルを使用する必要があります。20.04 サポート。最近リリースされた5.4カーネルパッケージは5.4.0-139で、推奨アップデートには5.4.0-144が含まれています。
