Did you upgrade aptitude first?

	aptitude install aptitude

This might solve many problems.

I also found aptitude lost in resolve madness while I had too many
foreign packages.  Check the list of manually installed packages

  aptitude search ~i\!~M -F "%p"

to see if you have some of them not provided by the repo pointed in
your one-line sources.list.  Play with =apt-cache policy= to see if
update are available for such foreign-suspected packages.
