Error: "Please install "network-manager" via your normal software channels."

[Katniss Everdeen]

I accidentally removed the network packages, I have downloaded them on another computer. When I try to install it. I get "Error: "Please install "network-manager" via your normal software channels. Only install this file if you trust the origin."

I can't click "Install" button, it's not lit up. What do I do?

if you go to 'software sources' then you can enable the LiveCD/USB. then you can mount the LiveCD/USB and use it to install network-manager

I've done this. I copied the deb files to the desktop, still have the same problem.

just install them from the software center (or synaptic, or apt-get, or w/e you use)

Software center is what I use.

I tried to install it via command line, but it didn't work.

try this

sudo apt-get update; sudo apt-get install network-manager

try this

sudo apt-get update; sudo apt-get install network-manager

Didn't work, probably because it doesn't have Internet.

if you enabled the liveCD/USB as a software source, that wouldn't matter

post the output of this:

apt-cache policy network-manager

Here it is, sorry for taking so long.

How do I install the package from the CD? All packages have that error.
