I can encrypt files perfectly fine when specifying a passphrase, but for some reason when I don't specify a password, python-gnupg returns with:
gpg: signing failed: Inappropriate ioctl for device
I use a docker container for encrypting and decrypting.
I came across this Github issue (https://github.com/keybase/keybase-issues/issues/2798), which suggests to run:
export GPG_TTY=$(tty)
I've added this to my Dockerfile, but I'm still running into the same issue:
RUN export GPG_TTY=$(tty)
I couldn't find anything related to --no-tty in the docs (https://gnupg.readthedocs.io/en/latest/).
Any help with this would be appreciated!
