ubuntu-cleaner is a package that you have installed from an outside ppa. It appears that the dependencies for the package are not correct as per the traceback the python modules dbus, via the python-dbus package is not available.
This is not a bug in Ubuntu so I am marking it as invalid. ** Changed in: six (Ubuntu) Status: New => Confirmed ** Changed in: six (Ubuntu) Status: Confirmed => Incomplete ** Changed in: six (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to six in Ubuntu. https://bugs.launchpad.net/bugs/1650892 Title: package python-six 1.10.0-3 failed to install/upgrade: sub-processo script pre-removal instalado retornou estado de saída de erro 139 Status in six package in Ubuntu: Invalid Bug description: failed to run ubuntu cleaner.
