Steps to reproduce the issue

Setup waldur-mastermind on any headless server
And try to buy any available service, you will get the above errors

How to fix this?

You can use Python xvfbwrapper

Basic usage


from xvfbwrapper import Xvfb

vdisplay = Xvfb()
vdisplay.start()

# launch stuff inside
# virtual display here.

vdisplay.stop()

Usage as a Context Manager:


from xvfbwrapper import Xvfb

with Xvfb() as xvfb:
    # launch stuff inside virtual display here.
    # It starts/stops around this code block.

Or you can use alternative of pdfkit named weasyprint
