The backend will not start and gives the following errors (I did try
re-installing but it didn't help)

<pre>Make sure that the old 0.27 packages are uninstalled properly. I have
seen things like this when libmyth-0.27 is still installed and that
prevented libmyth-0.28 from installing.

I even tried downgrading to release 0.27 and had the same issue.<br>
I've run with strace but its not showing me a lot <br>
