I am trying to install Debian kernel sources using the following commands -
sudo apt-get install linux-headers-$(uname -r)
It prompts me to insert the Debian disk to continue the installation.
Why is this so? I have used other Linux Distros and the default behavior seems to be to install from an internet repository.
How should I change the default repository location? i.e. configure online repo for Debian and offline one for Ubuntu?
