Ubuntu 12.04.4 LTS to 14.04.1 LTS upgrade: "no new release found"

12.04 14.04 server upgrade lts

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.

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
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.4 LTS"
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

  I have the same issue. @Chel I saw that too in my research, but the question is, when is "soon"?

  @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)

  @Dis Not if, as I said, it is random...

  @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.

  I haven't found any evidence to support that it is random... It says you should be able to upgrade from the 24th.

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.
