We started with an Ubuntu 11.10 for a server system. The upgrade to 12.04 went smoothly. Now I only want to upgrade to the next LTS release. However, the system keeps telling me that 12.10 is available. Although this is true, I want to stick to LTS from now on.
How do I switch the release-"mode"?
I want the system to act like I installed it from an LTS-image.
After logging into the system I am greeted by
Welcome to Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-63-generic x86_64) * Documentation: https://help.ubuntu.com/ New release '12.10' available. Run 'do-release-upgrade' to upgrade to it.
