First of all, sorry for bad english... As seen above, even though the server did not perform a delete command has failed. Why is this happening? How do I import my local files? (SFTP, FTP is not working now T_T)

Try

export LD_LIBRARY_PATH=/tmp/chroot/lib
/tmp/chroot/lib/ld-linux-x86-64.so.2 /bin/ls

First place I would start is by checking if that /bin directory is intact. You can do this by executing the following:

cd /bin
echo *

Could also have been the doing of someone who has comprimised your system and is looking to cover their tracks as well. First thing you likely want to do is load up a live CD and check the md5's. /bin/ls not found even though it exists.
