Daemon not starting

[davide]

Probably not a bug but a problem of my platform, but not sure.
Until yesterday I ran deluged (only daemon) on a Raspberry with Raspbian (a Debian distribution) and it worked perfectly.
Then, i reinstalled a clean image of the operating system, runned those commands to be up to date

sudo apt-get update
sudo apt-get upgrade

installed the daemon and the console with

sudo apt-get install deluged deluge-console

but when i try to start the deamon with the command

deluged

I get this strange error, which i have never seen before

Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'deluge==1.3.10' distribution was not found and is required by the application

My python version is

Python 2.7.12

Please help, I need Deluge :) Thank to all the developers, this is a great project!

Have you tried purging deluge and reinstalling?
