I’m trying to upgrade from 12.04 to 14.04 and the first point release for 14.04 is out, but when I do do-release-upgrade it says no new release found. Any ideas why it’s not showing the new release?

×Users of Ubuntu 12.04 will soon be offered an automatic upgrade to 14.04.1 via Update Manager.
— Ubuntu 14.04.1 LTS released
Try waiting a couple of days, it doesn’t look like 14.04.1 is available for LTS upgrades right now.
That ’-d’ means ‘development’ which usually means 'unstable and unfinished.’ Don’t do that in a production environment.
On 12.04, running do-release-upgrade -d will offer you an upgrade to 14.04, the most recent LTS. Running it on 14.04 will offer you an upgrade to the the current development release codenamed utopic unicorn which will become Ubuntu 14.10.
I tried to do the do-release-upgrade, but it is still showing that “No New Release Found”. Any idea when it might be available?
Ubuntu 12.04 LTS is supported till April 2017 while Ubuntu 14.04 LTS is supported until April 2019.
