When decrypting I get following error:
$ eyaml decrypt -s 'ENC and the key goes on here'
.gnupg --quiet --no-secmem-warning --no-permission-warning --no-tty --yes --decrypt) failed with: gpg: Sorry, no terminal at all requested - can't get input
I have checked my keys, everything is in order. At this point I am out of options.
gpg --edit-key <my key id>
