I'm trying to install libdvdcss2 and w32codecs in MEPIS 6.5. The feedback I get is:
The following packages have unmet dependencies:
libdvdcss2: Depends: libc6 (>= 2.5-0ubuntu1) but 2.3.6-0ubuntu20.5 is to be installed
The following packages have unmet dependencies:
w32codecs: Depends: libc6 (>= 2.5-0ubuntu1) but 2.3.6-0ubuntu20.5 is to be installed
E: Broken packages
-- yet, according to APT, "libc6 is already the newest version."

According to this review of MEPIS, a person could get a repository of non-free packages called Medibuntu that would include w32codecs and libdvdcss. I added this repository to my /etc/apt/sources.list according to the instructions for Feisty Fawn here:
Code:
echo "deb http://packages.medibuntu.org/ feisty free non-free" | sudo tee -a /etc/apt/sources.list
wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add - && sudo apt-get update
(Naturally, I logged in as root and took out the sudo.)

Any idea why my already-installed libc6 won't do the job? Do I need a different repository?
