I have seen in the past that fully offline installs may work better - is that the case here? By that I mean, do you get better results if you skip proxy configuration and sort that out later? In no way do I like that as a long term plan, just trying to get you unstuck.
The 22.04.2 ISO would be a LTS, it's just not soon - due Feb 2023 per https:/ /discourse. ubuntu. com/t/jammy- jellyfish- release- schedule/ 23906
