I am assuming that you are using Ubuntu or a Debian based Linux distro.
The installation guide for that is here:-
When updating, it is only necessary to follow part of the installation procedure.
Assuming that you are using the suggested directory structure, and that you have extracted things into /usr/share/manager-server
then firstly it will be necessary to remove the file ManagerServer.tar.gz from that directory. This is because, Linux will typically bring the file in as desired, but will add a suffix something like “(01)” to the downloaded filename as a way of simply identifying the original from the new. Therefore, the simple way (for me at least) is to remove the original file before proceeding to get the new one.
