I would assume that the variable $LFS is not set, so that the chroot-command tries to chroot to a non existent directory.
Please, please, please, do as you were advised several times before learn your basics on the command-line. If you had done so you would clearly see what is wrong there. As also stated several times before in your various threads, just simply copying the commands out of the book without understanding what they do will teach you exactly nothing.
It is a rather pointless exercise to do a LFS install without understanding what you are doing.

You chroot into the $LFS directory with also using the the env command. So having a look at at the env manpage it shows that with the -i option you start with an empty environment.
Otherwise it wouldn't make any sense. You chroot into $LFS, what use would this variable have inside the chroot?
As stated above, you don't know what you are doing there. It seems to me that you don't even know how to get the necessary info if you don't understand a command (or you just don't want to get it yourself). This way the whole exercise you do is absolutely pointless.

I think I will do it like druuna and will not reply to any of your posts regarding LFS until you learned your basics.

hi i TobiSGD
yes this may be solution right, inside chroot env command with no option will print environment variables(which we were previously set $LFS is /mnt/lfs)
