Failed to fetch in Kubuntu

Binary package hint: update-manager

This is the message when I try to update to the new version 8.04 (adept and synaptic) while "Configurando nuevos canales de software":

I'm not a skill user. ¿What to do? I didn't find information for this bug at your site. Sorry if it exists and I am repeating.

Running Kubuntu 7.10

Thanks a lot and sorry for my english.

Thanks for your bugreport.

This looks like your sources.list file contains a invalid section entry. There should only be "main restricted universe multiverse" but it seems for some reason you also have "web" there. Please fix that and then the upgrade should work as expected.

I convert this bug into a question as it seems more appropriate.

In Plugin Finder Service dialog, when adding totem-mozilla plugin, it asks if you want to add 'web' service. If you choose yes, it adds 'web' to source.list.
