I'm trying to setup the docker credentials, and it requires to initialize the gpg first.

root@remote_machine:~# gpg --gen-key

GnuPG needs to construct a user ID to identify your key.
Real name: NeededUser
Email address: [email protected]
You selected this USER-ID:
"NeededUser <[email protected]>"
Change (N)ame, (E)mail, or (O)kay/(Q)uit? O
We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

I have tried to set up the GPG_TTY variable, and it is set to /dev/pts/0. What variables are necessary for GPG?
