I was going through the build process to make the current Equuleus iso image using the Docker method and the make process errored out with this error:
W: GPG error: http://repo.powerdns.com/debian buster-rec-48 InRelease: The following signatures were invalid: EXPKEYSIG 1B0C6205FD380FBB PowerDNS Release Signing Key <powerdns.support@powerdns.com>
E: The repository 'http://repo.powerdns.com/debian buster-rec-48 InRelease' is not signed.
I found this Github Issue and started interacting there, yet while the signing key for the repo expired yesterday, it has been extended but all efforts to bring the updated signatures into the Docker key ring still results in the build failing with the same error. And having almost no experience with build scripts, I am at a loss as to how to fix this problem and am looking for any guidance I can get.
Thank you
