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
clarification:
- 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
dist-upgrade
does not technically perform a release upgrade. You're looking for thedo-release-upgrade
command. If you've got/etc/update-manager/release-upgrades
set toprompt=LTS
and the packages are available on your mirror it should work. If not, I would suggest verifying the packages on the mirror next.
