Getting the error an upgrade from vivid to xenial is not supported. I need to know how to manually upgrade from v 15.04 to 15.10 so I can then upgrade to 16.whatevs as per usual.

I have tried

sudo do-release-upgrade 

and used the software updater program, and both return the same error. I do not want to skip versions from 15.04 to 16.x, I just want to manually install 15.10 from my current version, and that should allow do-release-upgrade to fix the rest.

  • I don't think so. I don't want to skip releases, I just want to proceed up the ladder to the latest release and I can't. Using software updater gives me the error mentioned in my original post, and I can't see any other method of installing upgrades. I've tried sudo do-release-upgrade and get the same error. – Joel McKay Sep 29 '16 at 5:44

    was missing the -d. Finally got it working, thanks for the help :) – Joel McKay Sep 29 '16 at 5:55


software & updates -> Updates -> Notify me of a new Ubuntu version


For any new version

and run

sudo do-release-upgrade -d

I thought -d was for servers only, but evidently not.

  • -d is for development releases. – Waqar Alamgir Aug 12 '17 at 17:54
