I have an old 12.04.2 Ubuntu server. I want to update it to 12.04.5. But do-release-upgrade
would upgrade to 14 LTS.
What do I have to do in order to update only within my LTS release?
You should be able to accomplish this by simply keeping your system up-to-date with
sudo apt-get update && sudo apt-get dist-upgrade
No special upgrade techniques are necessary if you already using 12.04.
