+apt-get update
+apt-get install -y python3.8 python3.8-venv
+update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 10
+python3 -m easy_install -U pip
+python3 -m pip install -U setuptools wheel
+git clone https://git.webis.de/code-generic/code-webis-cmd.git /usr/local/share/webis-cmd
