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
start it instead with
ssh -Y localhost /opt/intelFPGA_lite/17.0/quartus/bin/quartus
the latter command will reliably avoid the MegaWizard hang (at least for me). No need to rename or reinstall anything.

Wow.. U are a true lyf saver. i had same issue. . Already killed half of my day struggling on Megawizard SCFIFO generation GUI sluggishness
with Ubuntu 16.04 and Quartus Prime 17.1
My installation path was different
ssh -Y localhost /home/quest/intelFPGA_lite/17.1/quartus/bin/quartus
Worked with no issues..
