Environement:

Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:   trusty

Linux gns3-iouvm 3.13.0-66-generic #108-Ubuntu 
SMP Wed Oct 7 15:20:27 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Running GNS3 version 1.4.0rc1 on Linux (64-bit) with Python 3.4.3 Qt 5.2.1.

When I add a cloud, I get the following error:

=> Warning: Cloud 1: Traceback (most recent call last):

    for interface in sorted(psutil.net_if_addrs().keys()):
AttributeError: 'module' object has no attribute 'net_if_addrs'

The same from python console:

>>> import util
>>> psutil.net_if_addrs()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'net_if_addrs'

According to psutils repository https://github.com/giampaolo/psutil/issues/626 Looks like method not available?

Back to GNS3 1.3.12dev1 (install from git repo) No such issue

[julien-duponchelle]

How psutil and GNS3 is installed?

Thanks for the report

[AJNOURI]

Actually, it seems that I installed it through both pip and apt:

$ sudo pip freeze | grep util

docutils==0.12
ipython-genutils==0.1.0
psutil==3.2.2

$

$ apt-cache search psutil

psutils - PostScript document handling utilities
python-psutil - module providing convenience functions for managing processes
python3-psutil - module providing convenience functions for managing processes (Python3)
glances - CLI curses based monitoring tool
gpsbabel - GPS file conversion plus transfer to/from GPS units
page-crunch - PDF and PS manipulation for printing needs

By the way 1.4.0b4 installed in a virtualenv works fine:

virtualenv virt_env/gns341 --no-site-packages
cd virt_env/gns341
sudo pip3 install gns3-gui==1.4.0b4
sudo pip3 install gns3-server==1.4.0b4

We need psutil > 3.0.0

But versions from apt doesn't provide the correct version: http://packages.ubuntu.com/trusty/python/python3-psutil

Should we check psutil version and have an explicit error message?

[julien-duponchelle]

I think we should probably check, sadly we can have the same issue with all the dependencies provided by apt.

[julien-duponchelle]

I just add a check. We should promote the deb package instead of pypi for ubuntu
