sources.list

For people using Debian—especially new users—it can be confusing to have the proper and correct entries in the /etc/apt/sources.list.

You should—of course—use a Debian mirror that is not too far away from you. The examples below contain the generic mirrors where you have to replace “XX” by your language/country code. Furthermore, replace CODENAME by the version you are running, you can find all available codenames on the Debian website.

I also used to have the entries for Marillat packages by default but decided to remove them. They become less and less relevant (for me) and change too much in the base system which makes it difficult to impossible to remove them again. If you still wish to use those, feel free to use them of course. For instructions see the Deb Multimedia website.

Because users usually do not do development, I left out the deb-src entries. If you need the sources, just duplicate all entries and replace the starting deb with deb-src in the duplicates.

Servers

Although my page is aimed at desktop usage, please don't use the above sources.list on a server. There it should look something like this.

Bullseye and older

Because many servers need the firmware for hardware to function properly, I added the non-free by default here. If you are running Debian virtualized, the non-free can be remowed.

# Make sure to replace CODENAME with the release codename you are running

LTS

Sometimes, especially on servers, it can happen that you need to run an older version of Debian to ensure stable production. In those cases you can use the LTS1) repositories. LTS is usually only available only for the i386 and amd64 architectures.

For current available LTS versions and the actual support end date, please check the Debian Releases, you should never run an OS that is no longer supported and thus won't receive security updates anymore!

A fitting sources.list should look like this:

sources.list
### /etc/apt/sources.list
# For LTS Releases
# Make sure to replace CODENAME with the release codename you are running
 
### Main Sources
deb 	http://deb.debian.org/debian/	CODENAME		main non-free
 
### Security Updates
deb	http://security.debian.org/	CODENAME/updates	main non-free
