I want to see a list of repositories so that I have added to Ubuntu.
How can I acquire such a list? Is there a command I can use?
There are two different places in Debian for source list files:
Most of the default source listings are in
/etc/apt/sources.list
While a few packages may add their own smaller lists to
/etc/apt/sources.list.d/
To view each of them, you can cat them individually. (like cat /etc/apt/sources.list, or cat /etc/apt/sources.list.d/*)
This is quite a familiar style in debian packaging. For instance apache keeps its common configuration in /etc/apache2/apache2.conf, while several other packages (like phpmyadmin) may add their own smaller configurations in /etc/apache2/conf.d/
