That's interesting, because I had configured hkp://keys.gnupg.net in
gpg.conf (deprecated, I know) with GnuPG 2.3.4 and was not able to
refresh Andrew's keys. Only after changing the keyserver option to
hkp://keys.openpgp.org, I received the updated keys.

`gpgconf --list-options dirmngr` returns hkps://keyserver.ubuntu.com,
though.
