[solved] GPG issue when building inside continer.

When building in docker container `image=archlinux:latest` i can't get `gpg --receive-keys` to work.

```sh
rybkafiga@cloudshell:~$ docker run --rm --privileged archlinux:latest gpg -v --receive-keys CB9387521E1EE0127DA804843FDBB55084CC5D84
gpg: directory '/root/.gnupg' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: no running Dirmngr - starting '/usr/bin/dirmngr'
gpg: waiting for the dirmngr to come up ... (5s)
gpg: connection to dirmngr established
gpg: keyserver receive failed: General error
```

I'm working on resolving an issue with [arch-travis](https://github.com/mikkeloscar/arch-travis) (Travis base CI script for AUR)
I know I can override pgp check in `yay` inside docker container by stripping of `gpgcheck` (e.g: `yay --nopgpfetch --mflags "--skippgpcheck") but beside testing if PKGBUILD is working I would also like to test if pgp signature is fine.

It looks like an issue with `dirmngr` configuration being left out without running inside fully fleged system as `gpg --import keyfile` works fine.

```sh
rybkafiga@cloudshell:~$ docker run --rm --privileged archlinux:latest bash -c "curl -s 'http://keys.gnupg.net/pks/lookup?op=get … 5084CC5D84'|grep -ozP -- '(?s)-----BEGIN.*BLOCK-----'|gpg --import -"
gpg: directory '/root/.gnupg' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: key 3FDBB55084CC5D84: 88 signatures not checked due to missing keys

```

Re: [solved] GPG issue when building inside continer.

Ok, figured it out: (need to specify keyserver with `gpg --keyserver` flag)

```sh
rybkafiga@cloudshell:~$ docker run archlinux:latest gpg -v --keyserver hkp://pool.sk
s-keyservers.net --receive-keys CB9387521E1EE0127DA804843FDBB55084CC5D84

gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: no running Dirmngr - starting '/usr/bin/dirmngr'
gpg: waiting for the dirmngr to come up ... (5s)
gpg: connection to dirmngr established
gpg: data source: http://194.94.127.122:11371
