Introduction
In order to avoid Debian to search for packages on a non-existent CDROM, which is most likely not present on a Linux VPS, you should change a simple parameter on the /etc/apt/sources.list
file. You need to modify the file if you get an output like this while using apt-get
to install default packages:
Media change: please insert the disc labeled 'Debian GNU/Linux 7.0.0 _Wheezy_ - Official amd64 CD Binary-1 20130504-14:44' in the drive '/media/cdrom/' and press enter
Open and modify the file /etc/apt/sources.list
vi /etc/apt/sources.list
You will see an output like this:
# deb cdrom:[Debian GNU/Linux 7.0.0 _Wheezy_ - Official amd64 CD Binary-1 20130504-14:44]/ wheezy main deb http://ftp.us.debian.org/debian/ wheezy main deb-src http://ftp.us.debian.org/debian/ wheezy main deb http://security.debian.org/ wheezy/updates main deb-src http://security.debian.org/ wheezy/updates main # wheezy-updates, previously known as 'volatile' deb http://ftp.us.debian.org/debian/ wheezy-updates main deb-src http://ftp.us.debian.org/debian/ wheezy-updates main ~
This file contains all your package sources. You might find a deb cdrom:[Debian GNU/Linux 7.0.0 _Wheezy_ - Official amd64 CD Binary-1 20130504-14:44]/ wheezy main
line indicating a local CDROM as a package source. Comment it out by placing a #
symbol at the beginning of the line and save the file.
You should leave it like this:
# # deb cdrom:[Debian GNU/Linux 7.0.0 _Wheezy_ - Official amd64 CD Binary-1 20130504-14:44]/ wheezy main deb http://ftp.us.debian.org/debian/ wheezy main deb-src http://ftp.us.debian.org/debian/ wheezy main deb http://security.debian.org/ wheezy/updates main deb-src http://security.debian.org/ wheezy/updates main # wheezy-updates, previously known as 'volatile' deb http://ftp.us.debian.org/debian/ wheezy-updates main deb-src http://ftp.us.debian.org/debian/ wheezy-updates main ~
Now that you have fixed the apt-get CDROM error, you are ready to re-synchronize the package index files and install your services on Debian:
Enjoy!
