WKS server problems

[Andrew Gallagher]

Hi, all.

I'm trying to follow the WKS instructions from the wiki[1] on a remote
VM, but it hangs at the key generation stage:

```
key-submission at keys1:~$ gpg --passphrase '' --batch --quick-gen-key
"$SUBMISSION_ADDRESS"


^C
gpg: signal Interrupt caught ... exiting
```

There are no rogue pinentry processes in the `ps` list. I've tried
pinentry loopback just in case, but to no avail.

Any idea what's going on?

gpg (GnuPG) 2.2.4
