obfsproxy can't be started on Ubuntu 16.04

How did you install obfsproxy?

package obfsproxy 0.2.13-1 (xenial), net(universe)

I'm tying to follow instructions on help.ubuntu.ru

$sudo apt-get install tor tor-geoipdb privoxy

$sudo nano /etc/privoxy/config

$ cat /etc/privoxy/config

# Generally, this file goes in /etc/privoxy/config

ServerTransportPlugin obfs3 exec /usr/bin/obfsproxy managed

$sudo service tor restart

$sleep ...

$cat /var/log/tor/log

Here obfsproxy is not accessible.

Next steep must be setting up bridges

Bridges info https://bridges.torproject.org/bridges?transport=obfs3

$cat /etc/tor/torrc

Bridge obfs3 <IP-address 1:port 1> <Fingerprint of bridge 1>
Bridge obfs3 <IP-address 2:port 2> <Fingerprint of bridge 2>
UseBridges 1
ClientTransportPlugin obfs3 exec /usr/bin/obfsproxy managed

$sudo service tor restart

...Also not working
