From searching for some of the messages in your log, it seems weird that it would be causing a problem but do you have a Netgear router?
Ok, so you wrote the hass os image to your internal SSD using kubuntu booted from a flash drive. Then when you booted hass os from the SSD you're getting networking errors not being able to download the docker image from ghcr.io.
Can you visit ghcr.io from other devices on your network?
Can you ping ghcr.io from the hass os installation?
If you can't ping ghcr.io can you ping google.com?
If you can't ping either then your network interface might have not been set up correctly and or hass os is missing drivers for you network interface.
Are you connecting over Ethernet or wifi?
Guess the junior dev they had building their systems hadn't figured out regex yet lol
Godspeed
It's very possible that movie had an influence on my career decisions lol
I grew up with my dad always doing work in and around the house himself and now as an adult doing the same with my house, so I wasn't completely going in blind. My last programming job was in the office furniture industry and that gave me a leg up having knowledge about casework, tabletops, etc. My brother in law was also a finish carpenter (now a job superintendent, but we work in fairly different areas/companies) and I had helped him with side work over the years.
As an ex-programmer that is now in the trades I can say my mental health is way better and my back hurts less these days since I'm not sitting in an expensive "ergonomic" chair all day. There are a lot of high paying trades that are far from back breaking work. Personally I got in to finish carpentry building science labs specifically.
There's also the added benefit that I like playing with computers again, when it was my day job I wanted nothing to do with them after work.
