missing install dependencies for gstreamer1.0

[henczati]

On Lubuntu 14.04 (trusty), after installation starting the application kept crashing with

Traceback (most recent call last):
  File "/opt/extras.ubuntu.com/pomodoro-indicator/bin/pomodoro-indicator", line 37, in <module>
    from pomodoro_indicator import main
  File "/opt/extras.ubuntu.com/pomodoro-indicator/share/pomodoro-indicator/pomodoro_indicator.py", line 27, in <module>
    gi.require_version('Gst', '1.0')
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 79, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Gst not available

It seems, the gstreamer dependencies were not included in the package.

------------------------------
Resolution(?):

I'm not sure which of the packages is truly necessary, or which of them are to be installed manually and which would be installed automatically anyway, but this is how I made it work:

1. I installed the following uninstalled packages manually:

  sudo apt-get install \
    python-gst-1.0 python3-gst-1.0 python-gst0.10 \
    python-gi-dev

but I still got the same crash.

2. I found the https://wiki.ubuntu.com/Novacut/GStreamer1.0 page and according to it did:

  sudo apt-get install \
    python-gi python3-gi \
    gstreamer1.0-tools \
    gir1.2-gstreamer-1.0 \
    gir1.2-gst-plugins-base-1.0 \
    gstreamer1.0-plugins-good \
    gstreamer1.0-plugins-ugly \
    gstreamer1.0-plugins-bad \
    gstreamer1.0-libav

(For me, only
    gstreamer1.0-tools \
    gir1.2-gstreamer-1.0 \
    gir1.2-gst-plugins-base-1.0
were unsinstalled, but I was not on a clean Lubuntu 14.04 install.)

After completing step 2 I could successfully start the pomodoro-indicator .
