If when attempting to update software or install new software in Ubuntu you find yourself being asked to insert the installation/live CD or if you find the following errors while trying to update your sources the following should help fix this error.

W: Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ – Release amd64 (20111012)/dists/oneiric/main/binary-i386/Packages Please use apt-cdrom to make this CD-ROM recognised by APT. apt-get update cannot be used to add new CD-ROMs

W: Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ – Release amd64 (20111012)/dists/oneiric/main/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognised by APT. apt-get update cannot be used to add new CD-ROMs

W: Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ – Release amd64 (20111012)/dists/oneiric/restricted/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognised by APT. apt-get update cannot be used to add new CD-ROMs

W: Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ – Release amd64 (20111012)/dists/oneiric/restricted/binary-i386/Packages Please use apt-cdrom to make this CD-ROM recognised by APT. apt-get update cannot be used to add new CD-ROMs

E: Some index files failed to download. They have been ignored, or old ones used instead.

In order to fix this you’ll need to open up a terminal and type:

sudo nano /etc/apt/sources.list

Now you’ll see something similar to the following:

From here add a # to any lines starting with “deb cdrom:” then save and exit nano (Ctrl+X, Y, Enter).

Now from terminal type:

sudo apt-get update

You should now be able to install and update all the things without the need for a CD being mounted.

Installing packages from CD in Arch Linux

Okay, so you have Arch Linux installed and let’s say you’re wifi isn’t working and you need the package “iwlwifi-3945-ucode-15.32.2.9-2-any.pkg.tar.gz” to fix this but you don’t have a wired connect. What do you do? Blast in your Arch cd, mount it, mount the packages sqfs file and install using pacman.

Mount cdrom:

mkdir /mnt/cdrom/
mount /dev/cdrom /mnt/cdrom/

Mount *-pkgs.sqfs:

mkdir /mnt/pkgs/
mount -o loop core-pkgs.sqfs /mnt/pkgs/
cd /mnt/pkgs/

Install pkg.tar.gz:

pacman -U package-name.pkg.tar.gz
