You can upgrade directly from one LTS to the next LTS (eg. > 10.04 to 12.04), but can only go from a non-LTS to the next release. > So, from 10.10 to 13.04, your upgrade path would indeed by the full list > of 10.10, 11.04, 11.10, 12.04, 12.10, 13.04. So I thought I'd try to do this. The text below is divided into sections. It's always something I wrote followed by something in an Ubuntu window from the upgrade process. The bottom line is that 10.10 wouldn't let me upgrade to 11.04. I started running update-manager. The first thing I see is this pop-up window: --------------------------------------------------------------------------- Your Ubuntu release is not supported anymore You will not get any further security fixes or critical updates. Please Upgrade to a later version of Ubuntu Linux. (close) --------------------------------------------------------------------------- After closing the pop-up I get to the main window where I click "Upgrade". This brings up the Release Notes window with the text below. I click the Upgrade button at the bottom of that window. --------------------------------------------------------------------------- = Upgrading to a no longer supported version = You are about to upgrade to a version of Ubuntu that is no longer supported. The target release of Ubuntu is '''no longer supported''' by Canonical. The support timeframe is between 18 month and 5 years after the initial release. You will not receive security updates or critical bugfixes. See http://www.ubuntu.com/releaseendoflife for details. It is still possible to upgrade this version and eventually you will be able to upgrade to a supported release of Ubuntu. Alternatively you may want to consider to reinstall the machine to the latest version, for more information on this, visit: http://www.ubuntu.com/desktop/get-ubuntu For pre-installed system you may want to contact the manufacturer for instructions. == Feedback and Helping == If you would like to help shape Ubuntu, take a look at the list of ways you can participate at http://www.ubuntu.com/community/participate/ Your comments, bug reports, patches and suggestions will help ensure that our next release is the best release of Ubuntu ever.

You can re-enable them after the upgrade with the 'software-properties' tool or your package manager. (close) --------------------------------------------------------------------------- Closing that window returns me to the Distribution Upgrade window which shows that it is fetching files successfully, but then it stops and an error pop-up window appears saying this: --------------------------------------------------------------------------- Error during update A problem occurred during the update. This is usually some sort of network problem, please check your network connection and retry.

(close) --------------------------------------------------------------------------- After that the update-manager closes and it's over -- no upgrade for me! Is there a way around this problem? Thanks in advance! Mike
