Dear Maintainer,

I noticed the following using cron-apt: when a repository rotates its
GPG keys, cron-apt does not act on the error message about the unavailable
GPG key. This makes cron-apt not report about updates until a manual run
of apt update shows there is a problem with this repository and this is
fixed.

I expected cron-apt to report this error because this holds back updates
when the GPG key for a repository is updated.

I ran into this with the Grafana repository. There were no messages from
cron-apt, but by hand I saw the key had changed:
