Install question: package download fails on first boot

[maya]

I can install OrbitOS, but on first boot the package download step fails once and then works after retry.

Is there a recommended check order for:
- network reachability
- DNS resolution
- package endpoint configuration

Any quick checklist would help.

Good troubleshooting question.

Recommended order:
1) verify default gateway and DNS
2) confirm Store package URL is reachable
3) check system time and TLS trust
4) retry after cache clear

We will add this as a quick-start troubleshooting note.
