From the LFS 7.2 book, chapter 6.4 :

Quote:

It is time to enter the chroot environment to begin building and installing the final LFS system. As user root, run the following command to enter the realm that is, at the moment, populated with only the temporary tools:

ok thanks
can you tell me the proper way to switch root user in Ubuntu ??

In ubuntu the root account is disabled by default so you have to use 'sudo' ie

Code:

sudo chroot "$LFS" /tools/bin/env -i \
.
.

I'm not 100% sure if sudo is the way to go. The root environment might not be fully set.

You can enable full root access in the following way:

Code:

sudo passwd root

Now root has a password and you can do the following to get full root access:

Code:

su -

See post #5

You might also want to have a look at this (as reference!!) : LFS 7.1 on Ubuntu 12.04

Do not use sudo, use su - to become root and then follow the book to the letter.

i tried without sudo but same situation

druuna · 12-13-2012, 09:51 AM

What is the output of the following command (as root)

Code:

echo $LFS

I'm guessing it is empty, and it should print /mnt/lfs (or whatever you decided to use). This was told right here (the moment you started using root to execute commands): 5.34. Changing Ownership

Quote:

Also, double check that $LFS is set in root's environment.

Please read the book more carefully.
