20.34. kb-00033: Booting Ubuntu Without External Access

20.34.1. Knowledge Base Article: kb-00033

20.34.2. Description

How to install Ubuntu without internet access.

20.34.3. Solution

Default Ubuntu ISOs will attempt to check internet repositories, this can cause problems during provisioning if your environment does not have outbound access.

To workaround this problem, you need to supply a DNS and gateway for your subnet. There are several ways to do this:

  1. Internal to Digital Rebar: Define Options 3 (Gateway) and 6 (DNS) for your Machine Subnet

  2. External to Digital Rebar: Adding default_route=true to the boot parameters and include a DNS server on the local subnet in DHCP
