E: Package linux-kernel-headers has no installation candidate root@server:~# Whats wrong?
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.
degree of certainty? 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?
Confidence 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!
