I found the key from another post earlier on the forum.
My question was why there’s no link to that page right next to the signature and download links, since a new user needs that key to check the signature.
Searching through public key servers thru gpg doesn’t seem safe, because anyone could throw up a key there called “f-droid”.
The 2 “f-droid” keys could confuse some of the new users all of the time or even all of new users some of the time.
The way it is now, I bet almost no new users bother to check the signature on a PC, before they download it again and install another unchecked copy on their Android.
