I ran the install, which completed successfully. There is a process insync running and not doing much, but I find no GUI. If I try to run from Favorites, I get a message that "It seems another insync app is running. Will quit now." Is this beta version CLI only, and if so, where is the documentation. I have never used insync before and am trying to get my QNAP NAS server in sync with my Google Drive account. Client OS is Ubuntu 17.10 64-bit, GNOME 3.26.2 (default).
