Dominique gave the right hint because the folder in the env variable didn't exist:
sage: env SAGE_DOC '/usr/share/doc/sage' The problem is solved by installing the package 'community/sagemath-doc 6.7-1' (on Manjaro Linux) and we can check: $ ls /usr/share/doc/sage/ ca/ common/ de/ en/ fr/ hu/ it/ output/ pt/ ru/ tr/ Now the question mark works again but as Volker noticed if you have a "conf.py" file in your working directory you will get an error. Thank you!
