After this step dpkg -b /tmp/warsaw/ ~/Documents/warsaw_18.04.deb I get an error:

dpkg-deb: error: conffile '/etc/init.d/warsaw' does not appear in package

Any advise?

@gnumoreno

I haven't seen this message while preparing the script, but maybe one of the first commands didn't execute as it should.
Probably this one: dpkg-deb -x ~/Downloads/warsaw_setup_64.deb /tmp/warsaw
Can you try running again? Only this time go with bash instead of shell. I've been having better results with it.
