Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  alien: Depends: debhelper (>= 3) but it is not going to be installed
  dpkg: Breaks: dpkg-dev (< 1.14.0) but 1.13.11ubuntu7 is to be installed
E: Broken packages

here is my /etc/apt/sources.list file

You have Gutsy but your sources.list file has sources for Dapper.
Generate a new sources.list file from here. Save file on Desktop and assign new_source name to it. Open Terminal and execute this

cd /etc/apt
sudo mv sources.list sources.bak
sudo mv ~/Desktop/new_source sources.list
