GPG agent forward on Debian: setting pinentry mode 'loopback' failed: Forbidden

Hi Andrew!

I solved this issue finally! What a weird UI ...

So ..., apparently, it's not enough to tell the gpg-agent which tty needs
to be used via GPG_TTY!
You also have to do:

> I guess something is wrong on the local machine.

export GPG_TTY=$(tty)
gpg-connect-agent updatestartuptty /bye >/dev/null

Now, when I try to decrypt a file on the remote machine, pinentry opens a
dialog on the local machine.
If the password is properly typed, the decrypted file is printed out on the
remote machine!

This took quite a while to figure out!





Imagine there's no countries
it isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace
