I installed Ubuntu Server 12.04 from CD onto a machine with no Internet connection. Originally I did not select the Samba file server task during installation, but now I want to install it. I have tried "sudo apt-get install samba" and "sudo apt-get install samba4" but the packages cannot be found.
I assume the necessary packages are on the CD. Do I have to explicitly mount the CD? If so, what should I mount it as?
I have found answers to questions about upgrading packages from the Internet, or installing lesser-used packages using apt-offline. But that seems unnecessarily complicated.
