The drivers in my Ubuntu were broken after an update (Nvidia driver, the driver for wireless and even the driver for mouse I think) and can't even use the OS properly. What I did is, I installed another Ubuntu as partition in order to try access and recover my files from the original. I found out that there was a way to access the original OS (partition) and run commands in it using chroot, however, I think the commands are still running in the original OS' environment. I can't download updates since the driver for wifi is broken.

What I want to do is download the updates in the new OS, and apply them into the old. Is there any way I can do this? Thanks a lot
