ECCN/ Country of Origin for Ubuntu OS

Ubuntu is legal everywhere.

While this answers the legality question, it does not clearly define the ECCN of Ubuntu. From my understanding, Linux (and most distributions) are classified under 5D002 because some security features that deal with encryption. Since it is open source, it is eligible for license exemption TSU. Having a more official statement regarding this would be wonderful.

You can download Ubuntu from servers located in many countries.
There are 276 mirrors in more than 60 countries.

I doubut, the export control matters if you are downloading it from Brazil or Uzbekistan. Many of those mirrors are in countries not in the Wassenaar Arrangement.

There's also bittorrent which downloads from whoever is downloading at the time.

Scott, you should note that Canonical's headquarters and primary mirrors are not located in the US, so there is no particular reason why US law should apply here (unless you happen to be downloading specifically from a US mirror site for some reason). You should refer to UK law instead.

Agreed,

I was simply trying to put this into context as a response to the original question, and shed more light on the issue. If you are loading Ubuntu on a computer in the US, and shipping that laptop overseas, US export controls theoretically come into play, (though they may not matter as far as licensing is concerned, since they are eligible for an exemption anyway given that Ubuntu and Linux are Open Source software).

Thanks for all this feedback - I really appreciate it. Assuming U.S. export controls wouldn't apply, what about U.K.? Isn't U.K. a Wassenar member & isn't it accurate that license exceptions aren't available out of U.K.?

Fair enough; and it's true that the UK is part of the Wassenaar Arrangement, so I would expect that Canonical has needed to concern itself with export control in the past (full disclosure: I am a Canonical employee, but am not a lawyer and not typically involved in such matters).

I'm not sure that a community site like this is a good place to get a legal answer, though. http://www.canonical.com/about-canonical/contact has various contact addresses for Canonical, and you should be able to get an authoritative answer that way.
