repositories for chrubuntu

[herbert tamayo]

Hi, I'm using chrubuntu on my samsung arm chromebook, almost all works great, but I have these questions:

1. can I use any repository in my chrubuntu? for example the repos for ubuntu 12.04? checking my sources.list I have these activate:

deb http://ports.ubuntu.com/ubuntu-ports/ precise-security main restricted
deb-src http://ports.ubuntu.com/ubuntu-ports/ precise-security main restricted
deb http://ports.ubuntu.com/ubuntu-ports/ precise-security universe
deb-src http://ports.ubuntu.com/ubuntu-ports/ precise-security universe
deb http://ports.ubuntu.com/ubuntu-ports/ precise-security multiverse
# deb-src http://archive.canonical.com/precise partner
#deb http://ports.archive.canonical.com/precise partner
#deb-src http://ports.archive.canonical.com/precise partner
deb-src http://ports.ubuntu.com/ubuntu-ports/ precise-security multiverse

as you can see, I tried to use precise partner but it did not work, so I would like to know what repos can I use

2. is there a way to get rid off the google chromium os? I'm not using the default operating system, and I would like to add more room to my chrubuntu, so I would like to know how unistall chromium

3. chrubuntu is an accepted distro for canonical? in case of not how can I help to that distro?

regards

@1: what does "sudo apt-get update" tell you?

well this time I could update my apt-get and also I could download all the necessary package, so the first questios is solved, but i would like some help with the other ones.
