I think that I identified the issue. This is the libdns (dirmngr/dns.c) problem when hostname is not FQDN.
If you change it to FQDN, you can see that it tries to search adding the domain name.

• gniibe claimed T4021: dirmngr: dirmngr/dns.c issue with 127.0.0.1.

I tested on Debian with local dnsmasq. For usual setting, no problem.
If /etc/resolv.conf has nameserver 127.0.0.1 and the service by dnsmasq somehow stops, and we have another nameserver nameserver somewhere-not-local the issues/19 matters.

• werner triaged T4024: "Clean" does not remove superseded subkey signatures as Normal priority.

• werner triaged T4025: `gpg --with-sig-list --show-keys` does not show all the signature packets from stdin as Low priority.

--shows-keys is not a debug command to show the inetrnals of an OpenPGP message. It does the same as creating an empty homedir, importing the keys and running -k. Thus there is no way to get to the internals of an OpenPGP messages.

i'm having trouble just assembling the two signatures over the subkey with 2.2.8 in a single homedir. in particular, when i try to do the following with a new, clean test GNUPGHOME, then i see only one signature on the subkeys afterward:

Although "certificate" is used for OpenPGP revocations, it is technically a signature.

thus far every packet type has been a three-letter string, right? I'm looking at "Field 1" in doc/DETAILS. adding a 4-letter packet type seems like it could be trouble if someone has done the dumb thing of assuming the field is fixed-length.
