View Full Version : [ubuntu] install packages from live usb Urgent!!!

August 16th, 2010, 12:06 PM
okay so I was having trouble with pulse audio and completely obliterated pulse audio from my machine in order to prepare for a reinstall of pulse audio. this also uninstalled a few other packages that I needed to enter gnome....or kde..... so when I try to login via gdm(?) my password will not authenticate (when I enter via xterm or tty the password is accepted). to solve this I need to know

#1 how can install packages off a live usb drive from Terminal
#2 learn how to access a wifi network under terminal to use apt-get

any help would be great

i'm at school right now so It's kinda important :(

I guess that means adding the live usb as a repository to some program like synaptic on xterm
or telling where I could find packages and use dpkg

I have a similar problem, I had the infamous kernel problem in 10.10 (the one where everything installs fine but dpkg returns an error when configuring the kernel), so I erased the kernel I hopes I could reinstall it problem free. It gave me same problem so I rebooted....now it doesn't boot Ubuntu.
I know that doesn't help, but hopefully it will be noticed....
BTW.. maybe the above was unnecessary....have you already solved this problem??

I found what might be the answer here:http://www.tecnoupdate.com.ar/2010/10/30/como-restaurar-grub-con-un-live-cd-de-linux/ (for those who can read spanish)

Its actually a guide on how to reinstall grub from a live usb, but I'm pretty sure the commands they give can be the answer:
Mount your linux partition somewhere (for simplicity's sake, lets just say that your partition is /dev/sda1 and you mounted it on /tmp/part)
Mount it by:

sudo mount /dev/sda1 /tmp/part The site then says to install grub by:

sudo grub-install Śroot-directory=/tmp/part /dev/sda.I assume we can just substitute grub-install with apt-get (or whatever command):

sudo apt-get install "x" Śroot-directory=/tmp/part /dev/sda.Where "x" is whatever you want to install.
Hope this works.

Also, can anybody who knows how to do the above (install packages from a live usb to a hd install) post if what is the way of doing it.
