Unable to enter Chroot environment at 7.4 in the booklet.

Azureian · 08-17-2023, 01:18 PM

Hello, I am experiencing an issue where when I run the commands:

Code:

chroot "$LFS" /usr/bin/env -i \
 HOME=/root                   \
 TERM="$TERM"                 \
 PS1='(lfs chroot) \u:\w\$ '  \
 PATH=/usr/bin:/usr/sbin      \
 MAKEFLAGS='-j4'              \
 /bin/bash --login

It displays

Code:

chroot: failed to run command ‘/usr/bin/env’: No such file or directory

I have read many forums and still can't figure out how to fix this.
I tried fixing the symlinks, but it did not work.

My $LFS variable is set to '/mnt/lfs'

Running 'ls -l /usr/bin/env' returns:

Code:

-rwxr-xr-x 1 root root 48536 Sep 20  2022 /usr/bin/env

Here are my permissions:

Code:

drwxr-xr-x   3 root root  4096 Aug 16 22:58 var

LDD for '/usr/bin/env'

Code:

        linux-vdso.so.1 (0x00007fffd9283000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8c5b459000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f8c5b667000)

ls output:

Code:

bin  etc  lib64       proc  sbin     sys    usr
dev  lib  lost+found  run   sources  tools  var

I would appreciate it if someone could inform me of what needs to be changed.

If it matters, I am running Kali 2023.2a 64bit on VMware Workstation 17.

Then you must have /mnt/lfs/usr/bin/env for this command to work.

It should work if LFS is correctly set at the time the chroot command is given. Have you been doing this build in stages? If so, you need to visually check that LFS is set at the start of each stage.

@emerson: here is the version from the book

Code:

chroot "$LFS" /usr/bin/env -i   \
    HOME=/root                  \
    TERM="$TERM"                \
    PS1='(lfs chroot) \u:\w\$ ' \
    PATH=/usr/bin:/usr/sbin     \
    /bin/bash --login

Do both files exist (in /mnt/lfs) with sensible sizes/content?

cheers,
