Please see this - https://stackoverflow.com/questions/53380099/how-to-solve-the-dbus-import-error-in-travis-ci
As per https://docs.travis-ci.com/user/languages/python/#travis-ci-uses-isolated-virtualenvs, Python builds run in a virtualenv, and dbus is a 3rd-party module. You need to pip install it.

I’m getting

The command "pip install dbus-python" failed and exited with 1 during .
Requested 'dbus-1 >= 1.8' but version of dbus is 1.6.18
Xenial reports to have dbus 1.10
(Trusty seems to only has 1.6 available so you probably won’t be able to apt-get anything newer, either).
So you need to migrate to dist: xenial. Or use an older version of dbus-python.
Also the link I gave earlier says that you shouldn’t run with system site packages.
