gpg/gpg2 key creation just stops after entering passphrase

[Nemesis]

I've just installed Ubuntu 18.04.3 LTS mini (to use as a server)

But when I'm trying to create a new gpg/gpg2 key it just stops after I've confirmed my passphrase.. nothing happens after that.

It don't freeze, I can stop it with ctrl-c
This one was running for an hour before I stopped it.

Any suggestions?

Not anyone that recognize this issue? Maybe there is something missing that I need to install, since this is a minimal setup?
