無法使用 debmirror 創建 apt 鏡像

我試圖在我的本地機器上創建一個鏡像，但我無法驗證 gpg 簽名。

遵循以下步驟：https ://help.ubuntu.com/community/Debmirror

我在 /home/ubuntu/mirrorkeyring 下創建了trustedkeys 和 /var/repository 下創建了儲存庫文件的唯一區別

創建密鑰：

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

從我的mirrorbuild.sh：

export GNUPGHOME="/home/ubuntu/mirrorkeyring" 

執行mirrorbuild.sh：

  Failed to download some Release or Release.gpg files!

我只是嘗試使用 root 從標準 .gnupg 文件夾中讀取文件並工作。
