Debmirror GPG Key not verify error



I have an issue with Debmirror and the old/new GPG Key of VyOS. I try with the old GPG Key and nothing, with the new GPG Key and nothing too.

I added three GPG Keys (from the Wiki of VyOS and the website from the referer) and nothing. To mitigate this, I put the no verify GPG option on debmirror, but it’s not recommended.

What can I do?

Thanks in advance.
