I have been through most of the duplicates for this question, and still can't find an answer. I may have missed one but hopefully this isn't a duplicate!

Having a problem with updates. I get the "failed to download..."message followed by "Check your internet connection", which is clearing working fine as I am on it now.

I click details and get the following

E:Some index files failed to download. They have been ignored, or old ones used instead.**

All the faults have "maveric" somewhere in them, so I have gone to settings and unticked all the Mavarics I can find, but this problem is still happening. Any ideas?

Many thanks
