[gdelta9]

Hello,
im trying to use chroot to install a package using live cd to my kubuntu installed system.
i do what is indicated in an ubuntu how to.In moe detail i do this:



cd /
sudo -s -H
mount -t ext3 /dev/sda2 /mnt
mount -t proc proc /mnt/proc
mount -t sysfs sys /mnt/sys
mount -o bind /dev /mnt/dev
chroot /mnt /bin/bash


And then when i run



apt-get install sysv-rc


i get this error



dpkg: `update-rc.d' not found on PATH.
dpkg: 1 expected program(s) not found on PATH.
NB: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin.
E: Sub-process /usr/bin/dpkg returned an error code (2)


Any ideas how to overcome this?
Thnx a lot in advance!!!!
