I am trying to execute chroot command by changing the root in ubuntu machine.
Let me explain the situation.
I was mounted an ubuntu image in /mnt/ubuntu directory using follwoing command : mount /dev/mapper/loop1p1 /mnt/ubuntu
it was successfully executed. so finally i want to install new package in the ubuntu image which is ther /mnt/ubuntu . In order to execute the chroot command i was setting chroot environment by following commands:
mount -o bind /dev /mnt/ubuntu/dev
mount -o bind /proc /mnt/ubuntu/proc
mount -o bind /sys /mnt/ubuntu/sys
The above commands also executing successfully.
finally i am trying to install linux-image kernel package on mounted image which is there in /mnt/ubuntu.
chroot /mnt/ubuntu dpkg -i tmp/linux-image.deb
chroot: failed to run command `dpkg': No such file or directory
I think you need to have a look in /mnt/ubuntu when it's mounted -- it seems it does not contain files necessary for chrooting (or booting). Either some important directory is not being mounted, or you do not have a complete Ubuntu install on /dev/mapper/loop1p1.
first i have taken one ubuntu image which is ubuntu-flat.vmdk .
this i have converted into raw format using qemu converter
qemu-img convert ubuntu-flat.vmdk -O raw ubuntu-flat.raw
i find out the free loop device . suppose i have taken loop5 in /dev/loop5 location.
losetup /dev/loop5 ubuntu-flat.raw.
kpartx -a /dev/loop5
mount /dev/mapper/loop5p1 /mnt/ubuntu
mount -o bind /dev /mnt/ubuntu/dev (for this befor i have created dev directory in the /mnt/ubuntu location manually)
mount -o bind /proc /mnt/ubuntu/proc(proc also created before executing)
mount -o bind /sys /mnt/ubuntu/sys(sys also created before executing)
next i am trying to execute
chroot /mnt/ubuntu dpkg -i /tmp/somepackage.deb
