Great!!! Thanks Bob!
I ran the installation script without any issues - all went very well and have the 3 second blinky :slight_smile: This was done on two RPi-4 boards with 8-Gig Ram.

I copied the test scripts from a different RPi running Raspberry Pi OS and got this result:

ubuntu@k8s-node-0:~/examples$ date;python3 /usr/local/share/zymkey/examples/zk_crypto_test.py;date

Looks like around 90 seconds…

The Raspberry OS test run:

Around 97 seconds to run the test script…

Notice the python3 call in the Ubuntu version :slight_smile:

So far things are working as expected - I plan to do some more testing this weekend but want to say THANKS for getting this working in Ubuntu 20.04 LTS.

I expected the Ubuntu version to run a bit faster given it is running 64-bit OS vs 32-Bit and the processor speed in the RPi-4 is a bit faster than the RPi-3 I tested against.

Humble request - can we get 20.10 groovy gorilla support as well? It should be as simple as providing the apt packages for groovy on your aws storages, based on what the script describes for focal.

@kontrasec

We usually target the LTS releases, not the short-term releases. Out of curiousity, what aspects of 20.10 do you need that are not included in 20.04 LTS?

Regards,

Bob

20.10 is the first version that supports desktop mode for a pi 4. I was trying out a workstation pattern.

Admittedly this is a low-volume usecase.

@kontrasec - For us to turn a repo and test and support Groovy Gorilla is obviously a little more than just getting it to work. That said, If you would like to try things out, you should be able to point at our focal repository and install on 20.10. No guarantees all will work but here are the steps:

  1. Bring up 20.10. Update/upgrade and install curl.

sudo apt-get update; sudo apt-get upgrade -y
sudo apt install curl

  1. Download the install script to your PI4

curl -G http://s3.amazonaws.com/zk-sw-repo/install_zk_sw.sh > install_zk_sw.sh

  1. Edit Line 53 and set distro=focal

Change
distro=`lsb_release -c | cut -f2 -d$'\t'`
To
distro=focal

  1. Make the script executable and run as sudo

chmod +x install_zk_sw.sh
sudo su
./install_zk_sw.sh

Good luck!
