Hello,

Michael Rohleder <mike@rohleder.de> writes:

These failures were due to the 'DejaVu Sans' font not being available.

This is now fixed, along with an updated Weasyprint and some of its

dependencies, as of commit c601e2bf9adb05dc9dd9f3a565f693e968eb785c.

Thank you for the report!

Closing.
