Manual client update remotely not working

Hello there,

My urbackup server (ubuntu) not connected to internet directly so it can not download the latest client files. I check the documentation that how to update client manually, but remotely. I try to put the correct files (“update” folder from repository to /var/urbackup) try to restart clients and server, but nothing happened.

Client side (Windows 7), the silent install and client update is enabled.
