bash: ./lmcrypt: No such file or directory
As per this post, it looks like you should install the lsb package:
sudo apt install lsb
This should give you the required package on /lib64/ld-lsb-x86-64.so.3 (just tested it on Ubuntu 16.04.7 and it does).
As an answer so that this question does not get orphaned. The elf interpreter for the binary does not exist on the target system. The interpreter exists by default on REL-compatible systems but not on Ubuntu 16.04. Using apt-get install lsb might help but I cannot verify since the OS is already past end-of-life.
