I'm trying to access all of the repositories but i am unable to change the settings in the software center, command line, or right from the source list. I have a hypothysis that it may be due to unistalled updates but when i run "sudo apt-get install update" it says that it is unable to locate package update. help?
You are having some confusion about the syntax of
To get the most updated list of all the software, you do:
sudo apt-get update
For installing packages, you have tell apt-get what to install:
sudo apt-get install package
You were mixing above commands. To modify your repositories, you could either write in dash "Software Sources" and add/modify/deactivate repositories or editing directly the
sudo vim /etc/apt/sources.list
Remember that each time you do
sudo you are giving yourself god-like powers over your system, use the power with prudence and responsibility.
