General situation:I need to port a Qt project from MS Visual Studio 2010 to Linux (Debian).In VS 2010 I have Qt v.4.8.1, but in Debian it is Qt v.4.6.1. This difference prevents me from porting, as some features are not present in 4.6.1.In Debian I am using the stable Squeeze repository. My experience with this OS, and Linux in general, is zero.The Issue:Because the highest available version of Qt in the Squeeze repo is 4.6.1, I decided to enable multiple repositories, and get the more recent package from Wheezy instead.To add Wheezy I performed the following actions:Edited /etc/apt/sources.list, where I included:deb http:// ftp.debian.org/debian/ wheezy main  deb-src http://  ftp.debian.org/debian/ wheezy mainEdited /etc/apt/apt.conf.d*:APT::Default-Release stable APT::Cache-Limit 50000000However, it hasn't worked. I can't select the needed package from Wheezy because when I open Synaptic I get this error:Wow, you exceeded the number of descriptions this APT is capable ofI don`t know how to solve with this problem.All I need is to upgrade Qt in Debian. Am I doing this the hard way? Is there  a much simpler solution?
