Control: tags -1 + upstream This is definitely an upstream problem. In my normal maintenance of my Gentoo system I updated to gnupg 2.1.20, and it now also fails on the host system unless I load the ipv6 kernel module, so the problem was introduced somewhere between 2.1.15 and 2.1.20.
I'll now check 2.1.22, and if it still fails I'll report a bug upstream.
