I don't have physical access to the server at the moment and I want to upgrade to 18.04 clean fresh (if possible) from the existing install I'm running now.

As no physical access is possible I'm thinking that a couple of things need to stay:

  • sshd running
  • networking so I can connect
  • user/password
  • /home if possible

By clean install I mean that I want to go as close to a new 18.04 install as possible and I'll rebuild my system myself.

Any ideas?

Sometimes the answer to a question is:

Please, don't do this!

Because you might have a full rsync backup, but it's not about the backup: It's about the restore! How long is the restore going to take? How are you going to restore if you don't have access?

Unless you have all of the following:

  1. Remote console access!
  2. A full bootable off-line back-up (E.g. CloneZilla even if it's on a 128GB USB Stick or a 1-2-4TB USB HDD)
  3. The off-line backup drive contains a small 64 GB bootable partition containing a customized CloneZilla environment that will let you ssh into it to be able to do the restore.
  4. 18.04.1 (never install the first version of an OS, that is true under any OS whether it's DOS, NetWare, Windows, *nix, BSD, ...)

If all of the above is true, just do a do-release-upgrade

¯\_(ツ)_/¯
