I'll probably have to check those out. As far as I understand, those are not RPi / Raspbian based.

We need couple of things for software (which are currently OK with Neuron based stuff):

• OS security updates (ie. apt update & apt upgrade should do expected things)
• Java JRE should work

We are planning to use these devices to run our existing data collector package (which is java-based). Also, our customers require that Linux-based stuff should have support for OS security updates.

Can you confirm that these are OK ?

Unipi Neuron S103-G has only GPRS module, right ? It's a bit too slow for our applications.

I wonder if there are any plans to integrate a faster 3G or 4G module to Neuron series ?
This otherwise so great stuff, but falls behind competition in mobile communication now.

Same happened to me yesterday, running apt update & apt upgrade on fresh UniPian-Neuron-2019-01-07-v1.9 results in broken system.

I'm sure that I did just the same steps a couple of weeks ago without any problems.
