Hi there, I am having an issue whenever I try to install something. On Ubuntu Software Centre, I get a following error message when I try to install:


The following packages have unmet dependencies:

libcurl3:i386: Depends: zlib1g (>= 1:1.1.4) but 1:1.2.3.4.dfsg-3ubuntu4 is installed

Depends: libc6 (>= 2.4) but 2.15-0ubuntu10 is installed
and here is what I get when I run sudo apt-get -f install
