Can you do a pip show matplotlib
?
If that doesn't work, try running import matplotlib; matplotlib.__version__
on your system.
It seems like you are using a matplotlib that doesn't support QT5 and you have to update that to get opensnitch working.
Can you do a pip show matplotlib?
Sure:
$ pip show matplotlib

Name: matplotlib
Version: 1.3.1
Location: /usr/lib/pymodules/python2.7
Requires: numpy, python-dateutil, tornado, pyparsing, nose
you have to update that to get opensnitch working
Thanks, if I understand correctly what is happening, its my package manager that only provides the 1.3.1 version, and I need another (more recent?) version. So, yeah, not directly related to opensnitch, but more a dependency problem. But what is the minimal version required ?
You are actually having a few different problems
Ubuntu 14.04 is not packaging PyQt5. Ubuntu 14.04 is ancient by now.
We haven't made any official decision about this but me personally would like to be able to use fairly new libraries and such. I would say that our baseline should be the latest Ubuntu LTS which is 16.04.
Also you are trying to run on Python 2, as you can see in https://github.com/evilsocket/opensnitch/blob/master/bin/opensnitch#L1 Opensnitch is Python 3. I just created a PR that makes install.py crap out on this https://github.com/evilsocket/opensnitch/pull/47
Ubuntu 14.04 is ancient by now.
Well, Ubuntu 14.04 is an LTS and is supposed to "last" 5 years...
I would say that our baseline should be the latest Ubuntu LTS which is 16.04.
I understand that choice, of course. Given limited resources, you can't support all OSes.
Also you are trying to run on Python 2
No. I am trying to run opensnitch, period ;-) What it does under the hood, I don't (want to) know. But I see you changed some stuff in the install process in #47, I'll check that out and get back here in a day or 2, please don't close. Also changed my python alias, but for some reason it seems to stay on 2.7 (at least matplotlib, I have to investigate...)
And thanks anyway, keep on the good job.
That Ubuntu 14.04 is "supported" (as in by Ubuntu, not by us) only means that it's receiving security and bug fixes, not that it's guaranteed to run new software. I'm sorry if I sound a bit dismissive but I really think that one of the advantages of working on a new project is that you can depend on stuff that is a bit bleeding edge.
@evilsocket Can we close this one?
That Ubuntu 14.04 is "supported" [...] only means that it's receiving security and bug fixes, not that it's guaranteed to run new software.
Sure, got that. But as a standard Linux box and given the required packages, it "should" be able to make new stuff work. Seems this isn't so obvious, unfortunately...
Conclusion: I'm almost sure this is indeed not related to opensnitch but to Python and its infamous 2 vs. 3 problem. What I did:
git clone
) and installed (python setup.py install
)
but still, always stuck with python 2.7:
$ pip show matplotlib
---
Name: matplotlib
Version: 2.0.2-4065.gde2755c
Location: /usr/local/lib/python2.7/dist-packages/matplotlib-2.0.2_4065.gde2755c-py2.7-linux-x86_64.egg
Requires: numpy, six, python-dateutil, backports.functools-lru-cache, subprocess32, pytz, cycler, pyparsing
So you can close this issue if you feel it should be, I'll post here if I find any solution.
@skramm You might get it to work by actually using python3: http://packages.ubuntu.com/trusty/python3 and http://packages.ubuntu.com/trusty/python3-pip and then invoking python3
and pip3
respectively.
With that said the packages in 14.04 are ancient and I would not be surprised if there are some things that are not there.
If I was you I would just get with the times and upgrade ;)
I do have both python2 and python3. The problem is more related to the fact that with my distro, the default is python2. I'll try to manually change the symlinks, but this is probably going to break lots of other stuff.

Yeah, makes sense. But stability and long-term support is crucial to me, so I'm kinda reluctant.
You need to install python3-pip python3-setup tools and python3-pyqt5 and also python3-dev
And as you see from updated Readme file you need to run command as python3 setup.py install if you do not have python3 as default one.
I forgot to add the python3-pip as dependency but yeah its dependent to python3-pip the command you later use for listing or showing packages is pip3 not just pip which is symlink to pip2 on your system.

Fixed ! Here are my steps:
python3
instead of python
(see http://matplotlib.org/users/installing.html ),sudo opensnitch
runsThanks for support !
There's no reason why not to have python3 and python2 side-by-side on the same system. No need to mess with symlinks. I have both versions and everything works great (granted I run 16.04, not 14.04 which may be a bit harder due to other dependencies).
Using 2.7.12 as the default python
and using explicit python3
(or pip3
etc.) for programs that require it.
opensnitch
just needs to ensure python3
is used wherever it is required.
There's still at least one reference to python
in the README.md Install section (sudo python setup.py install
). This needs to be changed to sudo python3 setup.py install
- trivial to fix.
Thanks!
No need to mess with symlinks
Yes, I confirm. I did it, and a lot of stuff started acting weird and/or crashing on my machine! Quickly reverted to original...
Just gave a try on Ubuntu 14.04, and not much Python knowledge. Promising project, but after install, didn't run. FWIW, this happened: (could be unrelated to opensnitch, but as a lambda user, I don't know what steps I should take).
