Debian installation remove cd-rom apt source

Posted on Edited on Disqus:

A local CD can act as an APT repository, just as if it were a distant server. This feature is incredibly useful when you are installing Debian on systems without a fast internet connection or when you need to install packages from localized media. However, once the installation is done or if you prefer using online repositories, you might want to disable the CD-ROM source to avoid any unnecessary prompts.

If you don’t want apt-get to search the CD, you can achieve this easily by editing the /etc/apt/sources.list file. Here’s how to do it:

Steps to Remove CD-ROM apt Source

  1. Open the /etc/apt/sources.list file:
    To edit the file, you need administrative privileges. You can use nano or any other text editor you prefer. If you’re using nano, the command would look like this:
1
sudo nano /etc/apt/sources.list
  1. Find the CD-ROM source line:
    Look for the line that specifies the CD-ROM as a source. It will look something like this:
1
deb cdrom:[deb95amd64d1]/ stretch contrib main
  1. Comment out the CD-ROM source line:
    To disable this source, simply comment out the line by adding a # at the beginning of it. The result should look like this:
1
# deb cdrom:[deb95amd64d1]/ stretch contrib main

  1. Save and close the file:
    In nano, you can do this by pressing CTRL+X, then Y to confirm the changes, and Enter to exit.

  2. Update your package list:
    After making these changes, ensure your package list is up to date by running:

1
sudo apt-get update

By following these steps, you instruct apt-get to ignore the CD-ROM as a source, relying instead on your other sources for package installations and updates.

Whether you’re managing package sources or ensuring your applications are running smoothly, Debian and its tools offer robust solutions for both tasks.

Taking care of your system’s configurations thoughtfully can save a lot of time and hassle.
