Since Wireguard has been uninstalled on my system, I think it should remove also the "dietpi-wireguard.list" which is breaking apt.
Now everything seems to be nominal.

@XRay437
Thanks very much for your report.

Actually interesting that this missing key error does not appear on initial install of WireGuard... Thinking about it, addition a Debian repo to a Raspbian system should require to add the Debian keyring, however it seems not in this case, perhaps not as long as preferences limit it's use to the WireGuard package, not sure.

Jep that was intended but prevented by typo. Just fixed it, many thanks: Fourdee@770deb5
