apt-get upgrade fails because of glibc6

Question

I cannot upgrade my system anymore. I get the following error. What can I do to resolve this problem?

 apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run `apt-get -f install' to correct these.
The following packages have unmet dependencies:
  binutils: Depends: libc6 (>= 2.11) but 2.7-18lenny7 is installed
            Depends: libstdc++6 (>= 4.6) but 4.3.2-1.1 is installed
  cpp-4.6: Depends: libc6 (>= 2.11) but 2.7-18lenny7 is installed
  gcc-4.6: Depends: libc6 (>= 2.11) but 2.7-18lenny7 is installed
  libc-bin: Breaks: libc6 (< 2.10) but 2.7-18lenny7 is installed
  libc-dev-bin: Depends: libc6 (> 2.13) but 2.7-18lenny7 is installed
                Recommends: manpages-dev but it is not installed
  libc6-dev: Depends: libc6 (= 2.13-30) but 2.7-18lenny7 is installed
  libquadmath0: Depends: libc6 (>= 2.10) but 2.7-18lenny7 is installed

When I run apt-get -f install I get the following error

Preconfiguring packages ...

Answer 1

You might want to run `apt-get -f install' to correct these.

Answer 2

Upgrade to wheezy folled by downgrade to squeeze made it. Was a bit tricky, had to remove and reinstall some packages for this to work.
