According to Trusty Tahr Release Schedule, Ubuntu LTS 14.04.1 (first .1 version) was released two days ago. Unfortunately when trying to upgrade using the do-release-upgrade command I get the message No new release found.

Command line output:

root@foobar:~# cat /etc/lsb-release
root@foobar:~# do-release-upgrade 
Checking for a new Ubuntu release
No new release found

The threads upgrading LTS to LTS and no new release found make totally sense, but as I understand the first dot 1 version of Ubuntu 14.04 (14.04.1) has yet been released, so why can't I still upgrade LTS to LTS?

Is there a way to upgrade properly, not using the -d option with the do-release-upgrade command?

    According to the release instruction: lists.ubuntu.com/archives/ubuntu-announce/2014-July/000188.html Users of Ubuntu 12.04 will soon be offered an automatic upgrade to 14.04.1 via Update Manager Jul 26, 2014 at 14:40

    I have the same issue. @Chel I saw that too in my research, but the question is, when is "soon"? Jul 27, 2014 at 14:47
  • @Dis Who knows? It may be a chance thing, whereby only 10% of people requesting get it otherwise the download would be painful with all the requests at the same time. (Purely speculation)

    @Tim I meant if it was random like you said, someone must know that it's random. That's a valid answer if it is the case. Jul 28, 2014 at 9:29

Actually -p option works to run the release upgrade:

do-release-upgrade -p

Here is the explanation of the -p option:

-p, --proposed
Try upgrading to the latest release using the upgrader from Ubuntu-proposed

P.S. Also on #ubuntu IRC channel nobody seems to know what actually "triggers" the do-release-upgrade command to work properly...

P.P.S. Caution when upgrading from Ubuntu 12.04 LTS to 14.04.1 LTS, as grub will fail to update kernel list.

  • Nope, Checking for a new Ubuntu release /n No new release found Didn't work for me

    According to answers to this question, the Proposed repository can be unstable and isn't usually suitable for production systems. Even if -p does perform the upgrade (as it does for me), I doubt that it is "a way to upgrade properly," any more than -d is.
