Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bug report as separate attachments? This is very likely a duplicate of bug 571743. Thanks in advance.

I'm unsure how to upload multiple files for this error log. I will test some of the solutions for the duplicate bug first. It was very difficult to find answers to such issues.

Thanks

I have attempted the upgrade again, with a suggestion from the Duplicated bug, the solution for my, having both Ubuntu-desktop & xubuntu-desktop installed was to remove xubuntu desktop.

Removing Xubuntu-desktop allowed my upgrade.

Thanks.

Can verify the same problem existed with my xubuntu 9.10. Removing ubuntu-desktop allowed upgrade to proceed, as per workaround.

Suggest there is a problem to own here.

Thanks.
