No. You were asking if anyone else has encountered the issue, and I
replied by pointing you to the bug report of someone who also
encountered the issue.
The problem is that either there is no graphical pinentry, or there is,
but it cannot execute e.g. due to DISPLAY not being set, *and* the
fallback pinentry failed to open the terminal due to the fact that stdin
of the gpg process is not connected to a terminal. The latter can
happen for example when gpg is used in a pipe.
