Para mim, a exclusão da pasta .gnugpg ajudou:
sudo rm -rf ~/.gnugpg
Sempre que tento gerar uma chave gpg por meio do programa GPG do sistema, ela solicita meu nome, e-mail e senha, então tudo, exceto a janela principal do programa GPG, desaparece.
Ao usar o gpg key-gen
gpg: can't open '/home/jesse/.gnupg/random_seed': Permission denied
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.

Not enough random bytes available. Please do some other work to give
the OS a chance to collect more entropy! (Need 300 more bytes)
