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?
