I've got Natty Narwhal. I just installed ppa:nvidia-vdpau/ppa. However, I tried to sudo apt-get update and I got this:


W: Failed to fetch http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu/dists/natty/main/source/Sources 404 Not Found

W: Failed to fetch http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu/dists/natty/main/binary-i386/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

I figured it was just a faulty ppa so I tried a "ppa:purge" (that's supposed to be ": p" without the space in between) but I get the same error. At the end it says:


Warning: apt-get update failed for some reason
PPA to be removed: nvidia-vdpau ppa
Warning: Could not find package list for PPA: nvidia-vdpau ppa

I double-checked my /etc/apt/apt.conf file and it looks fine. It reads:


Acquire::http::proxy "false";

I'm out of ideas. Anyone else have one?

Never mind, I got it all figured out. Apparently the ppa I installed was just for older versions of Ubuntu, so I installed the newer one.

As for removing the faulty ppa, I still couldn't use ppa:purge, so I used Ubuntu Tweak. For reference, here's a link to show how to install and use it:
