Arch Linux failing while importing keys (due to use of GnuPG 2.0.22?)

[merginator]

I'm getting the following output when trying to bootstrap arch linux. I'm on the latest rev of image-bootstrap and a recently updated CentOS host:

Hi Dan,

I cannot reproduce the issue with GnuPG 2.2.19 on another distro so it might be a GnuPG problem.

I would ask if using another build host is an option to you but bug #64 will hit you after. I have pinned that bug just now to make it easier to see. It's unfortunate that Arch OpenStack images cannot be built right now but please note that Arch is a moving target so having Arch support work every day of the year would be a full time job...

[merginator]

I was able to test with CentOS 8, which comes with GnuPG version 2.2.9 and everything worked. I didn't run into issue #64 as it seems to be tied to the openstack flag, which I am not using. I'm not sure what minimum GnuPG version is needed, but maybe a version check is in order once someone's able to narrow it down.

[hartwork]

Make sense! Thanks for the update!
