Update errors

[dodgingspam]

I have a DELL mini with Ubuntu. When I attempt to run System Update Update Manager says: "Your system is up-to-date. The package information was last updated 304 days ago." So, I run "Check" unfortunately i get an error message box with the following:


Could not download all repository indexes
Failed to fetch http://dl.google.com/linux/talkplugin/deb/dists/stable/Release Unable to find expected entry main/binary-lpia/Packages in Meta-index file (malformed Release file?)
Some index files failed to download, they have been ignored, or old ones used instead.

How do I clean this and run a good update?

Thanks.
