upgrade to Ubuntu 10.10

Asked by srikumar

I am using Ub 10.04 with the latest online upgrades.

How to upgrade to Ub 10.10 ?

Do I need to wait until it is offered as an automatic upgrade ?

Thank you

The restriction to install LTS versions only was changed to enable all upgrades and the upgrade process to Ub 10.10 commenced. However the process was aborted with the following message:-

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

etc
etc

Any suggestions?
Thank you

10.04 is a long term support release (LTS) so the next LTS release will be 12.04. If you want to upgrade to the current short term support release, in update-manger, under the update tab, near the bottom of the window, Release Upgrade..Show me distribution releases: and a list, select normal releases instead of long term support releases., then you should have an upgrade button offered in upgrade manager the next time you run.

Fully update your 10.04 system before trying to upgrade to 10.10.
Remove uneeded packages
sudo apt-get autoremove
sudo apt-get clean
Then try the Upgrade again.

The above commands were run in Terminal
thereafter the upgrade process was restarted
and the same error message was seen, viz:-

n unresolvable problem occurred when calculating the upgrade:
E:Error,pkgProblemResolves:Resolve generated breaks, this may be caused by held packages.

etc
etc

any suggestions ?

The Full Text of the error message is as below:-
"
Could not calculate 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.

This can be a duplicate of bug 721306 and bug 658458 (and a dozen similar ones)

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.

Try this workaround: Open a terminal and enter the command:

sudo apt-get remove xserver-xorg-video-nouveau

and try the upgrade again.
