Obfsproxy error on Ubuntu 17.04

Question

I have Ubuntu 17.04 and have installed Obfsproxy: sudo apt install obfsproxy

Installation was successfull, so I run it:

sudo obfsproxy -v

Unfortunately, I get this error:

Traceback (most recent call last):
  File "/usr/bin/obfsproxy", line 6, in <module>
    from pkg_resources import load_entry_point

OSError: [Errno 13] Permission denied:

Any idea how to solve this?

OK, found the problem... I have installed some packages through pip before and it seems there are some conflicts in Ubuntu... So you need to install Obfsproxy to virtual environment:

sudo pip install virtualenv
virtualenv venv
source ~/venv/bin/activate
pip install obfsproxy

~/venv/bin/obfsproxy -v
