debconf: unable to initialize frontend: Dialog

And lots more error messages besides.

I get this when I do, for example,

# apt-get install less

Full trace:

debconf: unable to initialize frontend: Dialog

debconf: falling back to frontend: Teletype

I've installed apt-utils and libterm-readline-perl-perl, and I still get the same batch of errors (well, almost the same: now it doesn't try to fall back to Teletype).

I *think* that it wants to configure stuff, and ask me questions, but it can't, and (shockingly :-) google is no help (others have the problem, can't seem to find a fix).

SO: Any clues? THANKS!

simply install first dialog with

apt-get install dialog

jeff should add this to his script
perhaps he has it forgotten

Thanks gorgone, I'll give that a try.

EDIT: That worked! I can now install packages without complaint. Thanks again!

gorgone- thanks for the dialog tip; had the same problem and now it is solved. Took me a while though getting it via google.

In a debootstrap of maverick (Ubuntu 10.10) the following did it:

apt-get install whiptail

(the dialog package does not exist!).

On debian 7.2 I needed to install this pakages

dialog
aptitude install libgd2-xpm

to get the pakage "nginx" install without error
