Apt-get :: apt-setup not operational

Hello DSL gurus!
I'm a relatively recent Linux user, and fell very much for DSL because it seems to have been developed at a level of technical excellence that I value highly.
Here's an issue I have encountered:
having DL'ed and activated for use both dsl-dpkg.dsl and gnu-utils.dsl, I am unable to get apt-setup to work. The binary IS present where it's supposed to be, however, trying to invoke it by:
typing '#apt-setup' results in an empty prompt return, w/o any error message showing up.
It has been drawing my attention over the past couple of DSL releases.
Any comments and/or guidance are truly and deeply appreciated.
Best regards!

To edit your sources.list, type "sudo nano /etc/apt/sources.list".

-J.P.

Thank you for your prompt and resourceful response,
SaidinUnleashed!
Having the support of mentors like you is yet another good reason to enjoy DSL so much.
Be well, bye!
