Hi there,
I am having a bit of a problem with an upgrade of Ubuntu 10.04 LTS to 10.10. Normally I would just make a clean install, but the company I am working for wants an upgrade rather than a clean install. I have followed the steps in the Update Manager, and it shows that I can upgrade to 10.10. I click on the upgrade button and the upgrade starts, but then it bombs out with the following message:
Invalid package information
After your package information was updated the essential package 'ubuntu-minimal' can not be found anymore. This indicates a serious error, please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report.
I have checked the logs and find this:

I have checked my sources.list and the only problem which I had when trying to update packages was:
deb
http://deb.opera.com/opera/ stable non-free
So I have commented that one out.
Any ideas what I can do to fix this?
Thanks

Kim
