How do I upgrade an older version of Ubuntu Server (Jaunty, for example) to a specific later version (Lucid, for example) using the command line?
I'm concerned that dist-upgrade is going to update to the latest, which is not LTS
- has to be command line
- our internal mirror has removed the Jaunty images
- tried editing /etc/update-manager/release-upgrades to use only LTS versions, but it hangs. (trying to reach an outside server?)
Update: It seems Jaunty to Lucid is not possible (directly) ref, but my question was still for the more general case
