[ubuntu] No notification for 16.04.01 LTS

Hi,

I currently run Ubuntu desktop version 14.04 LTS, I've run Software Updater and I'm still not getting notification about 16.04 LTS being enabled. I've got setting to notify my about lts release but when I check available versions I'm getting nothing.

desktop:~$ grep Prompt /etc/update-manager/release-upgrades
Prompt=lts

desktop:~$ sudo do-release-upgrade -c
Checking for a new Ubuntu release
No new release found

I'm based in Ireland, perhaps new version isn't available here yet?

Regards
