Торификация gpg: где найти how to?

Torifying GnuPG on GNU/Linux
It is very likely both Tor and GnuPG will be in your distributions repositories. If you do not already have them installed, please refer to the documentation for your OS for more information on the packages.
Torifying GnuPG from the command line is a relatively simple task. Since v2.1, GnuPG uses dirmngr to facilitate communication with keyservers. To quote the documentation directly:

"The option --use-tor switches Dirmngr and thus GnuPG into “Tor mode” to route all network access via the Tor Network. Certain other features are disabled in this mode. The effect of --use-tor cannot be overridden by any other command or even be reloading gpg-agent. The use of --no-use-tor disables the use of Tor. The default is to use Tor if it is available on startup or after reloading dirmngr."

Another option is to insert use-tor into the ~/.gnupg/dirmngr.conf file.
For further information on dirmngr options in GnuPG, see ​this section of their official documentation.

Я запускал gpg-connect-agent --dirmngr 'keyserver --use-tor pgp.mit.edu' /bye
Я вписал в ~/.gnupg/dirmngr.conf use-tor
Но ничего не добился, torsocks gpg --keyserver pgp.mit.edu --recv-keys 0x4E2C6E8793298290 выдаёт

gpg: keyserver receive failed: Server indicated a failure
