Anthony Sottile <asottile@umich.edu> added the comment: should the minimum sphinx version be bumped and/or this reverted: https://github.com/python/cpython/blob/f7f0ed59bcc41ed20674d4b2aa443d3b79e72... this change breaks, for example, sphinx 1.8.5 while building for ubuntu 20.04 The directive used here requires sphinx>=3.2.0 I notice some other attempts have been made to make the docs more compatible with sphinx 1.x in this release as well so there might be conflicting directions here: https://github.com/python/cpython/commit/b63a620014b67a6e63d10783149c41baaf5... ---------- nosy: +Anthony Sottile _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue36675> _______________________________________
