On Raspberry Pi 2, how do I get beyond the 'Product Activation' dialog?

Raspberry Pi 2, Jan 2015 Raspbian image. Launching Mathematica results in a 'Wolfram Product Activation' dialog and I'm asked for an Activation Key. What do I enter at this point so that I can click 'Activate'?

Great, so I'm not completely alone....

I have the same symptoms: Mathematica/wolfram work for root user, but not for anyone else. Unfortunately the adding to the video group doesn't help, but also, I'm running Kali, rather than Raspian

Any ideas on how to debug this? Potentially this would require entries to the policy kit database somewhere below /etc/polkit-1/localauthority/... ???

I am new to Linux and Raspberry Pi (and need to stop saying that).

This worked for me. Just following the insructions worked.

Thank you Arnoud.

It is just a matter of finding the right expert at the right time.

To add a user that can run the Wolfram Language:

pi@test-pi ~ $ sudo adduser pi2
Adding user pi2' ...
Adding new grouppi2' (1004) ...
Adding new user pi2' (1001) with grouppi2' ...
Creating home directory /home/pi2' ...
Copying files from/etc/skel' ...
[...]

Add it to the 'video' group (required as part of a number of checks that the Wolfram Language is running on a Raspberry Pi):



pi@test-pi ~ $ sudo usermod -a -G video pi2

Switch to 'pi2' account, and run the wolfram engine:

pi@test-pi ~ $ su - pi2
pi2@test-pi ~ $ wolfram

Ha! Excellent. Thanks.

I agree it is a counterintuitive way to fail. The appropriate developers have been made aware of this issue.

OK, so, if Mathematica can't access /dev/fb0 and/or /dev/vchiq, it reports this as a problem with licence activation. Forgive me if I seem crashingly naive, but this makes no sense at all!

Mathematica on 2nd Pi2 fixed the same way. We can but hope there are enough good keywords in this thread to bring other sufferers to this solution. I'd still quite like to know why, though.

Thanks again, Ilian!

Mathematica needs appropriate permissions to talk to the GPU hardware, and the 'video' group can access the corresponding device in /dev.

yup, adding the user to the video group did the trick for me as well. Thanks!
POSTED BY: David Campagna

The user wasn't a member of the 'video' group, but it is now, and now Mathematica works. Thanks! So... What was going on there, then? There appears to be nothing on the entire RPi filesystem with that GID, as far as I can tell.

What user are you running Mathematica as? Is that user a member of the 'video' group?

sudo usermod -a -G video myuser

should do the trick.
POSTED BY: Ilian Gachevski

Aha! It works for 'root'. Permissions problem somewhere, then. Investigation continues...

I've tried uninstall and reinstall, unsuccessfully. I found file '/opt/Wolfram/WolframEngine/10.0/Configuration/Licensing/mathpass' which contains what looks like an activation key, and entered that, but it appears to have expired. How is anyone using Mathematica on Raspberry Pi if no licensing and activation information is available?

I'm having the same problem.
