ubuntu non-docker deps issue

pip install wont work on "system-managed" python instances by default. While tornado and pycryptome are in the repo (as python3-* packages) sslspk is not. Using `--break-system-packages` on the pip install command works but probably we shouldn't break a users system without permission first. I tried the proper way of using a virtual env but it currently isnt honored for the screen launches.

Trace the non-Docker dependency installation path and the screen launch commands described in the issue. Check how the virtual environment is selected or passed to those launches, and verify that installation avoids requiring --break-system-packages while the launches use the intended environment.
