I am trying to upgrade to Ubuntu 11.04. when I try I get this popup message from the upgrade manager:

Not all updates can be installed

Run a partial upgrade, to install as many updates as possible.

this can be caused by:

  • A previous upgrade which didn't complete
  • Problems with some of the installed software
  • Unofficial software packages not provided by Ubuntu
  • Normal changes of a pre-release version of Ubuntu

Button: Partial upgrade or Close

When I choose the Partial Upgrade

I get an error message saying:

can not upgrade An upgrade from Maverick to lucid is not supported with this tool

So I cant upgrade. How do I work around this, so that I upgrade?

Please add to your question the version of Ubuntu you're trying to upgrade from, it looks like you're trying to skip a version and the installer doesn't support that. – Jorge Castro Mar 8 '12 at 14:06
@JorgeCastro He's using 10.04. – James Mar 11 '12 at 0:46

it sounds like you are trying to upgrade from lucid (10.04) to natty (11.04). Which is not allowed.

You have to first upgrade to maverick (10.10) and then to natty (11.04).

you can however upgrade from 10.04 to 12.04 (LTS to LTS) if you want to wait until precise is released in April.
