I'm using 16.04. I ran apt update, apt upgrade, apt dist-upgrade, followed by do-release-upgrade.

I get this message:

Checking for a new Ubuntu release
No new release found.

I run lsb_release -a, and I'm still using 16.04.

Why is it not upgrading?

    This kind of question keeps coming up, and soon we'll have a good reference Q&A to explain that 18.04 LTS will not be ready to perform this kind of upgrade until the first point release 18.04.1 – SDsolar Apr 29 '18 at 02:58

  • sudo do-release-upgrade -d but I highly recommend doing this on a test partition with a clone of your 16.04 system. See: https://askubuntu.com/questions/1028604/bash-script-to-clone-ubuntu-to-new-partition-for-testing-18-04-lts-upgrade/1028605#1028605 – WinEunuuchs2Unix May 11 '18 at 17:44

As stated in the "Upgrading from LTS" section of the Release Notes,

Upgrades from 16.04 LTS will not be enabled until a few days after 18.04.1's release, expected in late July.

The idea behind this is that people who upgrade from one long term stable (LTS) release to another will most likely appreciate the improved stability of 18.04.1.

    Looks like this happened https://lists.ubuntu.com/archives/ubuntu-announce/2018-July/000234.html Yet No new release found – endolith Jul 28 '18 at 19:23

    @endolith I have (anecdotally) discovered that the new release is not available until this changelog page updates. At least for 16.04 and 14.04. As Wilbert's quote says, it takes "a few days" after release for the dist-upgrade to be listed. – Michael come lately Jul 30 '18 at 15:07

You need to use sudo do-release-upgrade -d prior to July 26, 2018 and drop the -d after that.

I highly recommend doing this on a test partition with a clone of your 16.04 system. See: Bash script to clone Ubuntu to new partition for testing 18.04 LTS upgrade

sudo do-release-upgrade -d will upgrade to the last release candidate. The final release is not in the repository yet. You might have to first upgrade to series 17 to get there.
