Ubuntu 10.4 wont upgrade to 10.10

sudo apt-get install update-manager-core

Then run:

gksudo gedit /etc/update-manager/release-upgrades

Change:
Prompt=lts
to:
Prompt=normal

Save the new file, close gedit and run:
sudo do-release-upgrade

Should do it

Thanks for the quick response, still have a problem however, after running 'suso do-release-upgrade' I get the following

Could not determine the upgrade

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be
caused by held packages.

This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug against the
'update-manager' package and include the files in
/var/log/dist-upgrade/ in the bug report.

not sure if I have unofficial packages installed - dont think so, only had it running a few weeks and havent really installed anything....

ok can you give the output of:

dpkg -l | grep desktop

Thanks

My dad had a problem with this. The problem can be rectified by running:

update-manager -d

in a terminal. However, I do not know if this will try to upgrade the computer to natty alpha 1.

If upon trying to upgrade, you get a message about it being a Release Candidate, you're probably alright, but this won't work if you start getting messages about 11.04, natty, alpha-1 etc

I hope this helps.

yes the -d means (d)evelopment which is natty

pkg -l | grep desktop =

ok you have the 'ubuntu-desktop' package which is needed.

Maybe someone else can contribute

This can be a duplicate of one of these: bug 663158, bug 658458 and bug 658581

If the package xserver-xorg-video-nouveau is installed, in several cases the 10.04 to 10.10 upgrade fails with the error message
"Could not determine the upgrade
An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu"

Several persons have reported that after removal of that package the upgrade was successful.

I cant see the xserver-xorg-video-nouveau package installed and I certainly havent installed it myself so im afraid that cant be it.

It's part of a default install, you are free to remove it as you wish

apologies - I see it now and have uninstalled it - upgrading seems to be working now

Thanks
