[X2Go-User] Ubuntu 16.04 break

[Jeff Sadowski]

After rebooting my server I am getting the following error message:

Connection failed. : /usr/lib/x2go/libx2go-server-db-sqlite3-wrapper
insertsession 52 euler

and the command line shows as follows
]$ x2goclient
QSocketNotifier: Can only be used with threads started with QThread
x2go-WARNING-1> English language requested, not loading translator.
x2go-WARNING-1> English language requested, not loading translator.
QObject::connect: No such slot ONMainWindow::slotCheckAgentProcess()
qt.qpa.wayland: Non-toplevel surfaces can't request window states

I do not know what happened.
euler is the name of the ubuntu 16.04 machine.
