No prompt at all in the console / ssh connection (and no graphics, so 
nothing to click on). So no manual cancelling from me.

Yes it is:
% tty
/dev/pts/5

And there is no other one (this is a FreeBSD jail):
% ll /dev/pts
total 0
crw--w----  1 netchild tty 0x190  8 Sep. 15:36 5

I only have two pinentry binaries installed, both are not for a 
graphical environment:

% ll /usr/local/bin/pinentry*
lrwxr-xr-x  1 root wheel   12B 31 Aug. 08:20 /usr/local/bin/pinentry@ -> 
pinentry-tty
-r-xr-xr-x  1 root wheel   71K  1 Sep. 00:13 
/usr/local/bin/pinentry-curses*
-r-xr-xr-x  1 root wheel   61K 31 Aug. 03:00 
/usr/local/bin/pinentry-tty*

% pinentry
