Hi - I’m getting the following errors running Mopidy. Any suggestions?  
I don’t really know python

```python

The important part of the error is:

```python
  File "/usr/lib/python2.7/dist-packages/mopidy/config/ __init__.py", line 11, in <module>
    from mopidy.config import keyring
  File "/usr/lib/python2.7/dist-packages/mopidy/config/keyring.py", line 8, in <module>
    import dbus
  File "/usr/lib/python2.7/dist-packages/dbus/ __init__.py", line 81, in <module>
    import dbus.exceptions as exceptions
AttributeError: 'module' object has no attribute 'exceptions'

```

How did you install Mopidy? From “ubuntu” in your hostname and the paths I see in the error I’m guessing it was installed from APT, on Ubuntu?

Can you provide the output of `mopidy deps` and `dpkg -l | grep python-dbus`? I’d like to know exactly which version you have of the `dbus` dependency which seems to be missing it’s `exceptions` module.

Hi

dpkg -l gives  
ii python-dbus 1.2.0-2build2 amd64 simple interprocess messaging system (Python interface)  
ii python-dbus-dev 1.2.0-2build2 all main loop integration development files for python-dbus

mopidy deps just gives the traceback which in full is
