How do I restore the default repositories?
There are now errors when updating and I cannot install most software due to a corrupted
/etc/apt/sources.list
file. Is there a copy I can download to replace it?
The file would be for Ubuntu 12.04 (Final Beta) in the United States.

apt-get update only for a specific repository
When I add a PPA and I want to install some of its content, it is quite annoying to re-update all my apt list using apt-get update.
Is it instead possible to only sync the content of a given repository?

Do files at /etc/apt/sources.list.d need to have an extension '.list'?
In /etc/apt/sources.list.d I have several files for custom repositories. All the names of those files end with .list.
Is it obligatory that files in that folder should end with that extension? If yes, where is that information written?
