I was trying to generate new GPG key on my Ubuntu 16.10 for GitHub. However, it ended with an error message gpg: Sorry, no terminal at all requested - can't get input. I tried gpg2 as well with no difference.
Including terminal output:
greeny@greenyNB:~$ gpg2 --gen-key

How can I fix this to be able to generate GPG key?
Thanks to Jens Erat for his comment, solution: remove no-tty line from gpg.conf.
