Ubuntu upgrade error

[The Mad Rapper]

Tried to upgrade to 9.10 through the Update manager, but something went wrong and it stopped. I have a 'no entry' symbol in the system tray and get this message when I try to use either the update manager or apt-get to complete the update:

E: Problem with MergeList /var/lib/apt/lists/gb.archive.ubuntu.com_ubuntu_dists_jaunty-updates_restricted_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

I have no idea what to do now...help!

Right, I have worked out how to sort out all of the error messages, basically be renaming the affected files to .old, but I now can't seem to get the O/S to upgrade to the new version.

I have tried the below without success - any ideas?

sudo apt-get dist-upgrade

I'll annoyingly answer my own question. The following steps resolved the issue, update downloading now:

sudo apt-get install update-manager-core

Then

sudo do-release-upgrade

Great feeling of satisfaction to sort it out
