I'm trying to setup the docker credentials, and it requires to initialize the gpg first.
Here are my steps:
root@remote_machine:~# gpg --gen-key
gpg (GnuPG) 2.2.4; Copyright (C) 2017 Free Software Foundation, Inc.
This is free software: you are free to change and redistribute it.

Note: Use "gpg --full-generate-key" for a full featured key generation dialog.
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?
I was using kitty as the terminal emulator. Switching to the konsole resolved it to me
Got the same issue using kitty as the terminal emulator, over ssh. Using xterm solved my problem. The thing is that at the end of the configuration, gpg ask for a passphrase in a kind of window that kitty may not support over ssh.
xterm gpg window
