do-release-upgrade Checking for a new Ubuntu release No new release found

My HTPC is almost appliance like, in the way I never upgrade it, i.e. this morning it was still running Ubuntu 11.04 Natty Narwhal… It’s also not very appliance like in that it’s also full of random development stuff that probably shouldn’t be on it as well as several different types of databases, my backup infrastructure and tons of other things you really don’t care for.

But not today. Today I was bored and decided the best use of my time was to replace MythTV with XBMC. Not only that, I figured I should probably upgrade from

      Ubuntu 11.04 (Natty Narwhal)
      Ubuntu 11.10 (Oneiric Ocelot)
      Ubuntu 12.04 LTS (Precise Pangolin)
      Ubuntu 12.10 (Quantal Quetzal)
      Ubuntu 13.04 (Raring Ringtail)
      Ubuntu 13.10 (Saucy Salamander)

That’s a lot of upgrading. It would have probably been better for me to just install 13.10 ..

But when I got to Pangolin, the 12.04 LTS EVERYTHING WENT WRONG!

rus@relax:~$ sudo do-release-upgrade -p
Checking for a new Ubuntu release
No new release found

OMG I hear you cry, much like I did. WHAT IS THIS??? I tried everything, apt-get update, turning it on and off again, throwing things at the TV, I even went outside and bought a coffee. None of the above worked. This was because I was stupid.

do-release-upgrade Checking for a new Ubuntu release No new release found

The reason for the error was because I’d arrive at an LTS release. And the do-release-upgrade configuration had changed to now *stick* to LTS releases and not upgrade any more. So as the new 14.04 LTS isn’t out yet (as we’re not in the future, dummy) it couldn’t find anything to upgrade to.

The fix is to tell the computer to just upgrade to the next release and not be so stubborn by editing /etc/update-manager/release-upgrades

# Default behavior for the release upgrader.

# Default prompting behavior, valid options:
# never - Never check for a new release.
# normal - Check to see if a new release is available. If more than one new
# release is found, the release upgrader will attempt to upgrade to
# the release that immediately succeeds the currently-running
# release.
# lts - Check to see if a new LTS release is available. The upgrader
# will attempt to upgrade to the first LTS release available after
# the currently-running one. Note that this option should not be
# used if the currently-running release is not itself an LTS
# release, since in that case the upgrader won't be able to
# determine if a newer release is available.

See how it says Prompt=lts? THATS JUST RUBBISH! Change it from lts to normal then rerun do-release-upgrade. Theres a good boy!
