Various SVG diagrams use fonts from the 'Ubuntu' typeface as the font in their
labels. These are currently substituted for other fonts at the moment.

The Wikimedia instances on Wikipedia/Commons (eg. upload.wikimedia.org) that
generate PNGs previews of the SVG files do not have these fonts installed.

This can likely be solved with a simple:

sudo apt-get install ttf-ubuntu-font-family

on the relevant clusters.

Not quite, but something like that puppetised.
