How to install lrzsz? on Ubuntu16.04 server

first of all, my local computer has been installed with zssh, to send files to and from other servers. Now I want to install lrzsz, on a CVM I bought so that it is very convenient to transfer files. I run 

sudo apt-get install -y lrzsz

has been installed, and the command sz also exists, but the sent file cannot be received locally. Is there anything else you need to set up?

Rz sz ssh scp
