elements/package-installs/extra-data.d/99-squash-package-install does
a "sudo -E package-installs-squash", however at least on Ubuntu the
default seems to be having env_reset defined, causing the environment
variables being cleared and thereby losing information about your
venv. As a workaround you could try to change the env_reset setting in
your /etc/sudoers.
