So how do I force upgrade from Ubuntu LTS to the next LTS without waiting for the point release?
According some sources,
"A device running Ubuntu 14.04 LTS will only tell you there is a new Ubuntu update after the first point release goes live. In Xenial’s case that’s July."
How do I upgrade now, then? Is going to 15.10 the only solution?
EDIT: question and answer are still valid for 16.04 to 18.04, but note that at least in some versions the wait is not until the first point release goes live, but until some information files in ubuntu.org about current versions are updated, which happens usually some days after the point release but not always nor automatically.
- The release notes state:
14.04 LTS to LTS upgrades will be enabled with the 16.04.1 LTS point release, in approximately 3 months time.
This is because Ubuntu wants things to settle down before the upgrade is made available to people who really would prefer to have a stable and successful upgrade. I ran into a few issues on a couple of upgrades on a couple of my servers from 15.10 to 16.04.
- If you really want the new shiney, then:
- make sure your system is fully up-to-date
- run the command
sudo do-release-upgrade -d
I asked a similar question over at askubuntu.
Just update your packages:
sudo apt-get update
sudo apt-get dist-upgrade
Then reboot, and upgrade to the latest version:
sudo update-manager -d
