Ok so I have tried everything under the sun but can't get into my sources.list to fix the duplicate and I think that's why my Software Center isn't working as well.
This is what I get when I do /etc/apt/sources.list
christina@owner-laptop:~$ /etc/apt/sources.list
bash: /etc/apt/sources.list: Permission denied
christina@owner-laptop:~$
Then, when I do sudo apt-get update, this is what I get:
christina@owner-laptop:~$ sudo apt-get update
