    Did you manually update the GPG key for the NextDNS repo? Problem was fixed months ago, just follow instructions on the post here:

      i receive an error on Step 2.

          rm: cannot remove '/etc/apt/keyrings/nextdns.gpg': No such file or directory

       Ah, keyring file must be in the alternate location of:

      /usr/share/keyrings/nextdns.gpg

      Replace in steps 2 & 3 the file location.

      Yes! Thank You!

      that subtle change effected the resolution.

      am now no longer seeing the error prompt when bringing up Discover. :D

      Follow up Questions:

      1. is this Signature error a one-off, never to be seen again? or is this frequent?

      2. if frequent, can the above steps affect the same fix?

      3. if frequent, what is the cause? can said cause be addresses at the User level?

       Ok all is good for you now.

      For the extra questions;

      1) No, I would not expect it to be very often, maybe around once every 5 years. The gpg key expiry date will tell you when it may well occur again, not checked the exact date myself yet.

      2) Once the key has been updated on the repo, then doing same steps again will resolve things.

      3) As mentioned before, the GPG key expiry date was passed so it was no longer valid. There’s not much an user can do to avoid this, if you want to keep security of your package manager intact. Just report the expiry here as soon as seen and hope NextDNS updates the key soon afterwards.
