I thought I knew the answer to this, but not quite. The problem seems to be related to the fact that my Lucid install is directly descended from Jaunty (Alpha 2 I think it was) – i.e. I haven't done a clean install on this particular drive since then, I've just been upgrading through the release and dev cycles.

Here's my /etc/lsb-release file:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu lucid (development branch)"

which looks correct. I thought I'd see what would happen if I ran:

sudo update-manager –dist-upgrade

This results in a pop-up message saying “[COLOR="Red"]An upgrade from 'lucid' to 'karmic' is not supported with this tool[/COLOR]”.

When I close the dialog, I see this message on the terminal:

paul@lucid:~$ sudo update-manager --dist-upgrade

[COLOR="Red"]ERROR:root:Bad upgrade: 'lucid' != 'jaunty'
[/COLOR]

So something in one (or more) of my files is still pointing to Jaunty. Can someone suggest which one(s) I need to check?

Cheers.

[COLOR="Red"]Afterthought: actually it's just really saying that the expected upgrade path is from jaunty to karmic, but I still don't know how to fix it! I didn't get any errors the other day when I updated my /etc/apt/sources.list to refer to lucid and did aptitude update/upgrade.[/COLOR]

:popcorn:It's not out yet.

Yep, I get that!

python-apt has not been updated to include a lucid profile which is what Software Sources is complaining about. update-manager -dist-upgrade is only meant to upgrade from one version of a distribution to another so I'm not even sure why you'd try it.

Hi, many thanks for your response.

I edited my post a few minutes ago when I realised I'd jumped to the wrong conclusion.

I only ran the update manager command thinking that it might help shed some light on the problem.

Cheers.

Suite: lucid ... Thanks. I almost made the mistake of just replacing the contents with your add. Every single release is listed there.

Thanks for the link. I'll read up on it to see what this files is all about. I didn't forget about this file, like the rest of you, I didn't even know about it. Started karmic at alpha 2.
