That’s right! If you didn’t know, powershell is (nearly?) completely cross-platform.
I’ve recently been working on a server status script for work and I chose to do it in powershell. It does threaded pings, generates html files, etc.
With zero modifications at all the script runs flawlessly on both Ubuntu Linux and my Orange Pi. All I had to do was extract the powershell tarball, chmod +x pwsh and run the script.
Truly awesome.
What blew my mind was Powershell was markedly faster on my Pi than it was on my Ubuntu server.
I’ll be posting more about the script soon, as I need to figure out some things still. But it will be released in due time. I really like it!

tzdata fails to upgrade on Ubuntu 23.10
If you’re getting a dpkg error about tzdata prematurely exiting, you need to get this file:
Ubuntu – Package Download Selection — tzdata_2024a-0ubuntu0.23.10_all.deb
Afterwards, install with dpkg -i tzdata_2024a-0ubuntu0.23.10_all.deb
Afterwards, you can do apt upgrade to upgrade to the latest one in the apt repo that was failing.
Hope this helps someone!

Installing Google Coral on Ubuntu 23.10
MAY THE 4TH BE WITH YOU!… and also this guide.
I have not tested it in Ubuntu 24.04 but it may work. Let me know in the comments if you try!
This brief guide has been revised from:
https://coral.ai/docs/m2/get-started#2-install-the-pcie-driver-and-edge-tpu-runtime
This will essentially be the first part of a few parts coming for Frigate and Home Assistant.
First, we need to setup the apt repository, and install the required packages:
echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list
curl -fsSL https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/google-coral-edgetpu.gpg
sudo apt update
sudo apt install gasket-dkms libedgetpu1-std
If gasket-dkms fails (it probably will — if it doesn’t, skip down to the udev rule section):
sudo apt purge gasket-dkms
git clone https://github.com/KyleGospo/gasket-dkms
apt install dkms libfuse2 dh-dkms devscripts
cd gasket-dkms; debuild -us -uc -tc -b
You’ll have a .deb file one folder up:
cd ..
ls *.deb
dpkg -i gasket-dkms-*.deb
We need to add a udev rule for permission to the hardware device:
sudo sh -c "echo 'SUBSYSTEM==\"apex\", MODE=\"0660\", GROUP=\"docker\"' >> /etc/udev/rules.d/65-apex.rules"
If you don’t want to use the docker group, replace docker in the udev command string:
sudo groupadd apex
sudo usermod -a -G apex your_linux_username
sudo sh -c "echo 'SUBSYSTEM==\"apex\", MODE=\"0660\", GROUP=\"apex\"' >> /etc/udev/rules.d/65-apex.rules"
REBOOT!
Verify the device is detected and available:
ls -alh /dev/apex*
crw-rw---- 1 root docker 120, 0 May 4 20:34 /dev/apex_0
Docker + Portainer + Frigate + Mosquito MQTT…
Update 9-02-2023: I’ve stopped using HomeAssistant as it’s just not for me.
Update 8-01-2023: Ok! I feel fairly confident with everything now. Inititally my plan was to just give some docker run commands that would get everyone up and running quickly. But I have since discovered Stacks in Portainer, and I feel this is a much better method for deploying containers. Especially since it offers an easy way to upgrade them. Truly hope to have something together eventually!
Update 7-18-2023: I’ve managed to get an iPhone, an OBS stream, and my Amcrest camera into frigate using go2rtc as a restream source. Guide is coming along nicely!
…guide will be coming soon. I am slowly learning it all this weekend. I am really enjoying Portainer. I have a camera arriving tomorrow, an Amcrest one, and hope to have everything up and running by next weekend. Then I can begin taking some screenshots for the guide.
The absolute mixture and mess across the internet has made this challenging at best. But I really want to run my own NVR!
Oh yeah, and I’ll include Google Coral AI support as well assuming the card I ordered works in the PC I’m using for frigate. Hoping to make use of the wifi card slot.
I’m using Ubuntu for the base OS. Personally, I enabled auto-login and screen sharing so I can remote desktop in to it. I may switch to just plain VNC later on but this is working well for me at the moment. As I’ve always been a Gentoo Linux guy, learning Ubuntu (well, Gnome) has been interesting too. I haven’t ran a window manager in YEARS!
