As a work around, please consider > build-depending on python3-sphinx instead. That's part of the bigger > goal to make python2 a little bit more obsolete. We can use python3-sphinx as a workaround (as long as python3-sphinx-bootstrap-theme is also installed, of course). $ make SPHINXBUILD="/usr/share/sphinx/scripts/python3/sphinx-build" -C doc/v2 html That works nicely. Depending on how the debugging goes on this bug, I will upload lava-server with this change in debian/rules etc. to prevent a FTBFS bug in lava-server complicating things. We are planning on moving to python3-only, probably during 2018 and certainly before django LTS becomes python3 only but that's not until April 2019. However, there is a lot of legacy code to remove before that can happen. -- Neil Williams ============= http://www.linux.codehelp.co.uk/
