Yes, tutor installation, everything completely default so far.  
I referred to your link, which I had seen and tried earlier. I tried the example given:  
`echo "git+https://github.com/open-craft/xblock-poll.git" >> "$(tutor config printroot)/env/build/openedx/requirements/private.txt"`  
and that goes through with no error. But when I try to rebuild the docker image with:  
`tutor images build openedx`  
I get the following lengthy error message:  
`Building image docker.io/overhangio/openedx:11.1.3`  
`docker build -t docker.io/overhangio/openedx:11.1.3 /home/ubuntu/.local/share/tutor/env/build/openedx`

```auto
