The Ubuntu sources.list generator, is a web application that can create custom sources.list files for various version of Ubuntu. The sources.list file tells the packaging system where it can look for software to install. The generator can add many additional sources, including those for proprietary software.
This is more of a curiosity question as I try to get a better understanding of apt and package management.
I'm seeing that in my /etc/apt/ and /etc/apt/sources.list.d/ folders I have very or sometimes identical files which have the extension of sources.list, sources.list.distUpgrade, sources.list.save, and so on.
What's the point of these duplicate or similar files?
I'm completely new to Linux. I installed Lubuntu 11.10 on an old Toshiba laptop which worked fine but the sound doesn't work. Working through the trouble shooting I tried to install the latest LinuxAlsaDriverModules through Synaptic Package Manager.
