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?
