[Chicago] Python 3.5 in Ubuntu???

As one of those security folks, Python has libraries like Scapy that make packet generation and packet analysis within python super-easy. Also bear in mind that the “Red Team” is offense (e.g. they try to break into stuff) and the “Blue Team” is defense (e.g. trying to secure stuff to attackers can’t get in). There has also been a push lately for a “Purple Team” (e.g. Red Teamers and Blue Teamers working together). I wont bore you with all of the madness going on in the InfoSec world, but in short, if it wasn’t for Penetration testing and “red teaming” companies would still be [a lot more] trivially easy to break into. Some of the efforts of trying to break in and attempt real-word attempts on an environment allows the defenders to know their weak points and attempt to address them.

Hi Randy,
This is really over my head, but I do know someone who is into security big time. ( Interesting that Python is frequently used to write scripts that attach themselves to executable files and then.... well, hack!!! ) I know there are at least two teams of hackers, the so-called "Red" team and the "Blue" team, and within those categories you have the defensive and offensive hackers. Interestingly enough, a lot of these people end up working for the government and big corporations because.... well, you gotta fight fire with fire. I do know that a lot of these companies, and I'm sure the Houston Police Department is no exception, will officially authorize these hackers to break into their system to see just how secure the system really is. It's like my paying the kid next door to throw a baseball at my front door window because I want to see just how strong the window's glass really is.
I got into computing really because of math. And I never really left my math roots. I need to learn more about web programming and cyber security because that's where the big jobs are, but still.... when I pick up a CS book I always head straight over to the chapters on searching and sorting. I guess that's boring stuff compared to web development and computer security, but it's what I'm comfortable studying.

I do not type very fast or for that matter even talk as fast as my mind thinks. When this question was first posed I was a bit surprised that no one was responding that this was not the trusted version. I have not learned enough about how trusted versions become trusted versions and not working for Innova or B of A or one of the other major companies using Python for production work and security sensitive applications I have to believe that they have folks who are producing in house solutions to these issues. With a desire to use Python in my civic hacking world I am currently working with the group I am part of from the group winning a city of Houston Hackathon for a Houston Police Department phone app. Once the phone app is complete the security issues become huge in the minds of the folks at the department. The current budget and structure of IT at the department somehow created the desire within them to approach us as hackers to do this app and I see hackers beginning to want more data from the department that would be useful. So a lot of words I guess to say where are the standards and security committees for Ubuntu and Python and how would a civic hacking organization interact with them?

Hey Evil Joel,
Thanks for the information. For right now I'm going to try to tame my urge to have "the latest and greatest" version. I don't even know everything that 3.4 has to offer, so there's no rush for me to dive into 3.5 just yet.
Thanks for letting me know about the LTS thing. For some reason I thought that Ubuntu 15.04 was an LTS release. I totally agree with your comment about security. These days when we've got elementary school kids playing around with software like OpenVAS and WireShark, computer users have to be very aware of privacy and security issues.

Hello All,
So, I'm assuming you tried to install this via the package manager, right?
There is no "Ubuntu 15.04 LTS". There is "Ubuntu 15.04" but it is not a
Long Term Support release. The next LTS release will be out in April
(Ubuntu 16.04 LTS) and will officially support Python 3.5.1. I never
bother with any versions of Ubuntu outside of LTS releases. I find
non-LTS releases to be too unstable.
Instead I would probably try to find a PPA for Python 3.5.
Unfortunately, there does not appear to be an official one but there is
this PPA that is updated by a community member:
https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes
Of course, there is some greater risk of using community maintained
software, especially with regards to security.
Good luck,
eviljoel
