software installing problem

[shariefbe]

Hello,
I am new to linux...when i try to install gcc in ubuntu 8.04...i am getting the below error.

root@sharief-desktop:/home/sharief# sudo apt-get install build-essential
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package build-essential is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package build-essential has no installation candidate
root@sharief-desktop:/home/sharief#


...i dont know whats the error is...can anyone tell me what to do for this?

Your sources.list looks fine. Try changing your download server to 'main' in Software Sources (System>Admin>Software Sources) and see what happens.
