Yeah, sorry. This is an old script. I have a newer script that I've uploaded. This one creates a .deb in the root of the emacs28 source directory. You have to press Enter a couple of times towards the end of the build.

I'm not using this script any more. Now I build emacs.deb packages using https://github.com/kelleyk/ppa-emacs. This works for both Debian and Ubuntu.
