Tested with containers on all supported distributions.
Debian 8 (Jessie) still has Python3.4 and an old pip3, which makes it
impossible to build typing module which is a requirement of "new" Sphinx
python module.
One cannot update to latest pip3 from within pip in Jessie's version.
One cannot get a newer pip from upstream because newer pip don't support
Python3.4 anymore.
One cannot build with python3-sphinx package from Jessie because the
package is too old (1.2.3) and does not have sphinx.ext.autosectionlabel
module which appeared in 1.4 version.
