I've tried many different ways:

I downloaded the file on the Skype website, which returned me this error "Cannot install ia-32-libs"

I followed this instructions https://help.ubuntu.com/community/Skype and here is what I got:

**W: Failed to fetch http://archive.canonical.com/ubuntu/dists/precise/partner/Packages/binary-amd64/Packages  404  Not Found [IP: 91.189.92.191 80]
W: Failed to fetch http://archive.canonical.com/ubuntu/dists/precise/partner/Packages/binary-i386/Packages  404  Not Found [IP: 91.189.92.191 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.**

I even tried this command line:

sudo apt-get install lib32stdc++6 lib32asound2 ia32-libs libc6-i386 lib32gcc1 skype

And this is what I got:

**Error: need a repository as argument
pandora@ubuntu:~$ sudo apt-get install lib32stdc++6 lib32asound2 ia32-libs libc6-i386 lib32gcc1 skype

I just don't know what to do anymore, if I can't use skype, I might as well not use ubuntu at all. Please, someone help
