apt dependency not installed with bootstrap.sh or axii self update

I recently updated my workspace in a virtual machine and the building step for the python module dbus-python failed. I then tried ./bootstrap.sh --apt in the axii directory to install the missing dependencies and the missing dependencies were correctly picked up by apt but the installation was aborted without me doing anything - which should not be the case from my understanding. Maybe there is something wrong with the apt call? Manually installing the required packages fixes the dependency issue.
