19.04から19.10への問題のアップグレード

ZfsにUbuntu 19.04ルートがあります。 19.10にアップグレードしようとすると、 here で説明されている問題が発生します。

here による解決策は、

initrd_device=$(${grub_probe} --target=device "${boot_dir}")

/etc/grub.d/10_linux_zfsの415行目で

initrd_device=$(${grub_probe} --target=device "${boot_dir}" | head -1)

何らかの理由で、/ etc/grub.d /ディレクトリに10_linux_zfsという名前のファイルがなく、10_linuxという名前のファイルが1つだけあります。

変更された10_linux_zfsファイルが提供されています ここ 。

10_linuxファイルを変更された10_linux_zfsファイルで置き換えるのが正しい解決策かどうか知りたいのですが。

これで何か助けていただければ幸いです。

編集：

この質問に対する応答が得られなかった後、私は自分の10_linuxファイルを変更された10_linux_zfsサンプルファイルで置き換え、アップグレードを続行することになりました。 mysql以外はすべてうまくいったようです。

Mysqlを再インストールすることもできますが、データベースを失う可能性があるため、可能であれば実行しません。誰かがこれを解決する方法について何か提案があればそれは素晴らしいでしょう。
