This is the same issue we had earlier with the hang of MegaWizard when trying to configure an ALTPLL instance. Probably an issue with Ubuntu's X display.

One simple workaround I found is to start Quartus through an ssh tunnel to localhost with X display forwarding:

When you normally start quartus with 


/opt/intelFPGA_lite/17.0/quartus/bin/quartus
