Solution

The best solution at the moment is to update weasy print when you update your OS

  1. Open up a terminal, and use Secure Shell (SSH) to log into your environment

  2. Change directory to the location of the virtual environment's root folder is stored

  3. Activate your virtual environment

    If you have changed directory into the virtual environment folder in the previous set, just modify the instructions to reflect that

  4. Update pip, then weasy print
