Don't care about this error.  It is shown but ignored.  Future
Pinentries might want to implement a yes button and gpg provides the
translation here.

You clicked on CANCEL or closed the window.

You canceled, gpg-agent could not unprotect the key and and thus you get
the error code.

Given that you said it worked in loopback mode - I assume the pinentry
is broken and returns Cancel due to other reasons.  Did you

GPG=$(tty)
export GPG_TTY

in your target's bashrc etc?  The simple tty pinentry is used and it
needs to know its tty - is /dev/pts/5 the correct one?  Try running
pinentry on the target directly:

$ pinentry
getpin

should show the prompt.  Does it - if not, strace the process etc.



Salam-Shalom,
