Hi @atripp
I have already tried to make an asset and then download gpg keys to my machine and upload to the asset and then use the url for the gpg key in the asset. I doesn't work, I don't know why.
But I know the same gpkey works in our old solution, which just mirrors the entire remote repository to a local server with rsync.
When I tried Sonatype, I also got it to work, but I don't remember exactly how.
