For example, although Ubuntu 18.04 LTS was released on April 26, 2018, you won't be able to upgrade directly from Ubuntu 16.04 LTS until the release of Ubuntu 18.04.1 LTS, which is expected on July 26, 2018. Upgrades from one Long Term Service (LTS) release to another LTS release are allowed, but they're delayed to give the new LTS release some time to stabilize. You can then go through the upgrade process again to go from Ubuntu 17.10 to Ubuntu 18.04 LTS. For example, if you have Ubuntu 17.04 installed and you want to upgrade to Ubuntu 18.04 LTS, the upgrade process will install Ubuntu 17.10.


In general, you can only upgrade from one Ubuntu release to the next release. For example, now that Ubuntu 18.04 LTS has been released, you can immediately upgrade if you're using Ubuntu 17.10. Whenever a new version of Ubuntu is released, upgrades are immediately available from the previous version. You should always have backup copies of your important personal data, but it's especially important to have them when upgrading your operating system-just in case.
