Am I too late to upgrade from 14.04 to 14.10 now? (2015/08/29)

When I the command to do the upgrade, it tells me that it cannot find any new releases:

ubuntu$ do-release-upgrade -c
Checking for a new Ubuntu release
No new release found

I changed the type of upgrade from lts to normal, but that did not help. That is, the very first time I ran do-release-upgrade, it told me that 14.10 would be next...

do-release-upgrade -c
Checking for a new Ubuntu release
New release '14.10' available.
Run 'do-release-upgrade' to upgrade to it.

Next I tried to run do-release-upgrade without the -c and the message saying that no new release available appeared.

Would I have to download a 14.10 ISO so I can upgrade to 15.04 (which is the goal here)?

    This is because you are running an LTS version. Just for the record, 14.10 is obsolete by now.

  • @Lucio, I already changed the prompt to normal, no luck. I'm afraid that "obsolete" means I cannot simply upgrade to 15.04 now... which rather sucks. Aug 30, 2015 at 3:51

    What is the output for do-release-upgrade -d? You can always upgrade using other methods.

As Lucio mentioned in a comment, you can always upgrade to a development version. That way I could first upgrade to 14.10 and then to 15.04.

This is done using the do-release-upgrade -d command to go from 14.04 to 14.10 (the -d is required because the official version is obsolete so only the developer version is available for upgrade.)

Once 14.10 was upgraded, I could upgrade to 15.04 in the normal way, that is, using the do-release-upgrade without the -d option.

So if you are late upgrading from an LTS or other version to a newer version, you may need to use the -d to go to an intermediate version considered obsolete.
