For this, you'd need to either remove the repository that was added
for updating Edge, or obtain the public key for that repository and
configure your system to recognize it (offhand I don't remember how to
do that latter, but I think it involves special syntax in the
/etc/apt/sources.list* file).
Usually, when I get a missing pubkey error, I simply search on the
missing key. Such a search turns up this page:
