I am trying to install the build-essential package per the instructions located here: https://help.ubuntu.com/community/InstallingCompilers
I get this error when I use the command apt-get install build-essential
:
Media change: please insert the disc labeled
'Ubuntu 12.04.1 LTS _Precise Pangolin_ - Release i386 (20120817.3)'
in the drive '/cdrom/' and press enter
When attempting to install the package through the Ubuntu Software Center, I get the following error: https://i.stack.imgur.com/rMIx5.png
Is there any way to install the package online only?
