Since !180, all keys are tried. This can indeed be useful but buries
the offending key in a long output log.
This stores a message containing the key and UID during processing and
prints them all at the end.
wkd_sync/archlinux-keyring-wkd-sync:
Ignore keys with SHA-1 self-signature (by hardcoding them in a readonly
array) so that they will not be synced from WKD.
The Arch Linux WKD setup does not contain keys with SHA-1
self-signatures anymore.
wkd_sync/archlinux-keyring-wkd-sync:
Add script to refresh existing keys of archlinux-keyring on user
systems based on the state of the distribution's Web Key Directory
(WKD).
Invalid or revoked keys are ignored.
