Perhaps we are talking about two different things.

It sounds like you're concerned about how much space it will take
to install the currently selected packages.  There is already a
guage of how much space is available and how much space your
current package selections will take on the selection screen
status bar.  Please read:


I was under the impression Brandon was talking about problems with
downloaded deb files filling up your partition before they were
installed.  What I was trying to say that although this surely is
a problem, it is just an implementation not a UI problem.  The
implementation should surely try to minimize downloaded remote deb
files filling up a local filesystem.

I can see several solutions to this implementation problem:

1) Include the size of all downloaded deb files in the "needed space"
     count on the status bar.
  PRO: It means downloading remote files will not fill you local
  CON: It means that you're needed space is artificially high.
       It is a hack.

2) Intelligently install packages to the system as you download them
     (i.e. download deb, install it, then delete it.)
  PRO: It means downloading remote files will not fill you local
  CON: You still need space enough for one package.

The thing is that every UNIX system needs a certain amount of
operating disk space.  You can not expect to run a UNIX system
with little to no avaiable disk space.  There should almost always
be enough avaliable disk space to do at lease option #2 above (unless
perhaps you're installing something like xbooks! 8) )

I repeat though, the UI has nothing to do with this implementation

I will pass this problem on to the appropriate person in the deity
