GPG error when using "stack download"

Question

When I start stack upload, I get an error message:

GPG_TTY environment variable not set (see man gpg-agent)

Cannot find gpg2 or gpg executable

The download will succeed, but the error concerns me.

What are the consequences of this error? Is there a way to avoid suppressing it?

Answer 1

According to the discussion in the comments, errors occur due to stack trying to automatically sign GPG packages that are downloaded from version 1.1.0 .
