Ubuntu – Doubts upgrading Ubuntu Server from 14.04 to 16.04

Ubuntu – Doubts upgrading Ubuntu Server from 14.04 to 16.04

14.0416.04do-release-upgradeserver

I want to upgrade from 14LTS to 16LTS.

I just tried it now on my 14LTS and received:

 # do-release-upgrade
 Checking for a new Ubuntu release
 No new release found

I’m not quite sure where to possibly start. High-level:

(1)SERVER1 ->
(2)HOST1 (uses approx. for a local cache) -> VPN->
(3)REMOTE_UPSTREAM_REPO ->
(4)Ubuntu servers

I control/manage (1) and (2), but don’t have access to (3).

Where might the issue be? Probably at (3)? What might I need from them?

I know I’m running 14LTS with the Xenial kernel, but perhaps that doesn’t mean they have all the Xenial repos at (3)?

  • I eventually got it all working with Debmirror, some custom modifications to the meta-release-lts file (see link in comments above), and a separate script to copy the dist-upgrader-all directories/files.

    Sorry, I don’t have all the steps detailed to post here…
