Nextcloud sync client icon does not show

Hi, I am running NC 17.1 server on Ubuntu 18.04 64-bit with Gnome III.
My NextCloud client is 2.6.1git
I cannot get the client icon to show in my desktop. The sync client is running on the same machine that hosts the Nextcloud server.
The sync client config file at /home/user/.config/Nextcloud/nextcloud.cfg is: (less the CaCert)
[General]
