To troubleshoot this issue.

First check the libcrypt is installed correctly.

ldconfig -p | grep libcrypt

If the path is correct then check whether /tmp is mounted properly.
mount command will give you the details about the mounting. if there is noexec option for /tmp mount then this will not work.

noexec – Do not allow direct execution of any binaries on the mounted filesystem

So remove the noexec option from /etc/fstab and remount as given below:

mount -o remount /tmp

This issue will be fixed.
