/etc/apt/sources.list

J1021

I am hoping someone can shed a little bit of light into best practice for /etc/apt/sources.list. Some hosts I see 2 lines in this file, whilst others have an additional line for some sort of security repo?

Is it vital to have the security repo included?

Just replace it with the default list from wheezy: https://wiki.debian.org/SourcesList

Use the debian sources list generator:

It's pretty important to have the security repo in your sources.list
