مشكلة عند تحديث منتدى Discourse

لقد قمت بتثبيت إصدار discourse الجديد بنجاح. لقد اتبعت التعليمات الموجودة في المستند أعلاه ونجحت معي. ولكن الآن أواجه مشكلة في الاستعادة من النسخة الاحتياطية.
لقد جربت استعادة نسخة احتياطية من سطر الأوامر ولكنني حصلت على ما يلي:

root@my_server:/var/www/discourse# discourse restore my_server-2023-06-20-033008-v20210922064213.tar.gz
