cannot install dhcp server

hi all

when i run:
sudo apt-get install isc-dhcp-server
i receive:
E: Unable to locate package isc-dhcp-server

i get the same when i try dhcp3-server

i am connected to net and have apt-get other packages so not sure whats going on here

any ideas people

did you try apt-get update ?

sure did, ended up sorting it by updating the source.list file!
thanks anyway :)
