Last Check: is $LFS == /mnt/lfs ?

• Make sure that LFS is /mnt/lfs
• Execute (copy and paste):

echo "===== ======="
echo "Check $LFS..."
if   [ -z $LFS  ] ; then 
  echo ERROR: There is no LFS variable  === ERROR ===
elif [ -d $LFS/ ] ; then
  echo === === === === === === ===  LFS is $LFS/ === OK ===
else
  echo ERROR: There is no LFS directory === ERROR ===
fi

• STOP: if the last line is not the following (and revisit Week 03 Assignment #02).

Check /mnt/lfs...
=== === === === === === === LFS is /mnt/lfs/ === OK ===
