Невозможно создать подходящее зеркало с помощью debmirror

Я пытаюсь создать зеркало на своем локальном компьютере, но не могу проверить подписи gpg.

Выполнил следующие шаги: https://help.ubuntu.com/community/Debmirror

Единственное отличие, я создал доверенные ключи в / home / ubuntu / mirrorkeyring и файлы репозитория в / var / repository.

Создание ключей:

mkdir /home/ubuntu/mirrorkeyring
gpg --no-default-keyring --keyring /home/ubuntu/mirrorkeyring/trustedkeys.gpg --import /usr/share/keyrings/ubuntu-archive-keyring.gpg

Из моего mirrorbuild.sh:

export GNUPGHOME="/home/ubuntu/mirrorkeyring" 

Запускаем mirrorbuild.sh:
