Today when I try to install packages in debian , I cant install form internet , But i am able to install from debian cd.
It throws me error as
Ign cdrom://[Debian GNU/Linux 6.0.0 _Squeeze_ – Official i386 DVD Binary-1 20110205-17:27] squeeze Release.gpg
Then my brother prasanna gave a link to correct this issue.
commnent all line in /etc/apt/source.list
copy the following lines
sudo apt get update
Then you can use internet to download package
