Whats wrong?

[falko]

Maybe Ubuntu has made some changes in their repositories since I wrote the tutorial.

What's in your /etc/apt/sources.list?

But I think you can leave out the linux-kernel-headers package.

[Ripper]

i'm sitting on the same linux-kernel-headers error. i'm holding for a definitive response before i procede with an install of a critical server build. my sources file was commented to remove the cd, but i recognized .de sources where mine are .us. assuming that really didn't matter, i stuck with state-side sources. is ignoring this package really going to be ok?

It doesn't matter.

I think so.

[Ripper]

I pushed forward with the install and discovered the linux-kernel-headers line was obsolete and covered by some of the other components. I removed it from the list of packages to install and everything is good. Thanks to Falko for speedy reply!
