FIXED! Offine TAILS_3.3+ARMORY_96.3 not working on Braswell, but works on others

[smallking]

 I can get armory to install and run offline in TAILS 3.3 booting off the TAILS USB on my desktop computer. However, same the TAILS/ARMORY usb does not work when I try to run it on a NUC5CPYH (Braswell N3050 Celeron).

I have physically disconnected the wifi adapter in the NUC. Armory reports that it installs successfully, without errors. But when I double click on the icons to launch offline nothing happens.


Setup:
I created a TAILS 3.3 USB drive and downloaded the following files to a persistent folder, installing the psutils before armory:

armory_0.96.3-gcc5.4_amd64.deb
python-psutil_5.0.1-1_amd64.deb


Works fine on the following:
i5-4460
ASRock H97M Pro4 m/b. (probably about 2-3 years old)

Tried:
Same problem with armory 96.4 RC2 - installs but does not launch

Cheers!

Celeron are cheap CPUs, most likely lacks a lot of silicon Armory optimizes for. You'll have to use one of the unoptimized builds:

Yay! Fixed as per your advice. Works using the gcc4.7 build on celeron.

However, I just purchased the NUC to use as an offline signer (dedicated sole purpose). Would you recommend ditch it and get a better model/chip - security wise? If so which one do I need?

Anyway many thanks for your advice and ongoing work!

NUCs can actually fit full sized desktop CPUs, they're pretty cool =D. AFAIK, the gcc4.7 build will run on anything x86 that can operate at least Debian Wheezy and equivalents (Ubuntu 12+). Celerons and other low profile CPUs (think 5W laptop chips) are fine for signing. The only thing you have to look out for is ARM CPUs, as I don't really bother building for those (you can cross compile yourself though).

Your primary security concern is not with the CPU but with making sure your signer is effectively air gapped.
