PostGIS Workshop page is broken

[robe]

I tried going here as it is referenced in upcoming PostGIS In Action book.

​https://postgis.net/workshops/postgis-intro/

To my horror -- it gave a 403. I'm guessing there is something malformed which caused the sphinx build to fail. Could also be updates I ran.

ssh robe@postgis.net
cd /var/www
#edit postgis_workshop_update.sh #uncomment out the exit
sh postgis_workshop_update.sh

Yields error

I'm guess my OS upgrades somehow blew out the templates packaged with sphinx.

Doing:

 pip install sphinx-rtd-theme

appears to have fixed the issure.
