Hi @muse-sisay, this looks good so far! Although I kinda think having a dialog interface with so many options will slow down the setup process because now you have to start making selections.

One of the key things to deal is eliminating the prompts that come mid-way through the setup process, for example,

• during installation of postgres
• setting up unattended upgrades

It would be good if the user has the option of deciding whether they wanna use the dialog interface or just the traditional setup as it is currently. So, maybe the script could be run like this

# this invokes the dialog interface
bash setup.sh --gui

or something in those lines.

Another option I was thinking of is providing some kind of *.ini or *.conf file where all the variables are set, and the setup script just reads from that file. But the password should still be entered by hand to avoid accidentally disclosing it, lol.
