I think that I fixed the problem, at least in all the cases that I
tested (including the failure to install sassc and pysassc [1]), by
resetting the information when the internal pkgcache is closed (which is
done before running dpkg, for example).

In any case, please do keep an eye on this in the near future just in
case (I am sure that you'll do it even if I don't ask :) ).


[1]
sassc fails:

  Unpacking sassc (3.3.2-3) ...
  dpkg: error processing archive /var/cache/apt/archives/sassc_3.3.2-3_amd64.deb (--unpack):
   trying to overwrite '/usr/share/man/man1/sassc.1.gz', which is also in package pysassc 0.9.3-1
  Processing triggers for libc-bin (2.21-9) ...
  Processing triggers for man-db (2.7.5-1) ...
  Errors were encountered while processing:
   /var/cache/apt/archives/sassc_3.3.2-3_amd64.deb

These 3 get installed:

  Setting up libsass0:amd64 (3.3.3-1) ...
  Setting up python-libsass (0.9.3-1) ...
  Setting up pysassc (0.9.3-1) ...

And afterwards, once the curses thing is reloaded, sassc remains to be
installed and the DL size field shows:

  DL: 0 B/11.5 kB


Cheers.
