Upgrade Desktop form 14.04 LTS "No new release found" [duplicate]

Solution 1:

Command do-release-upgrade -c -d at this moment will get 16.04 LTS

Solution 2:

Usually, LTS upgrades are not supported in the initial LTS-next. That is, 12.04LTS could not be upgraded to 14.04LTS, but only when 14.04.1LTS was released. I would expect the same to be true this time, and that you'll have to wait until 16.04.1 to be released. I don't know the planned release date, but it's usually about three months after the main release.

You will be notified when it's ready to be upgraded and you should not try to do it manually by entering commands unless you really know what you're doing. Upgrading LTS to LTS is more difficult than normal upgrades and for most people, it's more important, so this needs more time to be handled correctly.

The ".1"-releases are Ubuntus version of "Service packs". So in other words, wait until the first SP is released. I would guess it'll happen sometime in July.

Solution 3:

As of 9th May this still does not work

sudo do-release-upgrade 

But it worked for me with -d flag.

sudo do-release-upgrade -d

Solution 4:

the 16.04 LTS Final Release is not out yet. it will be released during sometime later today/tomorrow latest. try again then

Solution 5:

The 16.04 LTS Final Release is not out for upgrade yet but it will be released sometime later today/tomorrow.

To have a check you can simply do from terminal

do-release-upgrade -c

this will check if the actual release is open. If yes run the command

sudo do-release-upgrade

without any parameter.
