Since 20th june 2013 I have tried running the software updater in ubuntu 12.04 LTS however it runs but returns this error
W:Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/precise-updates/main/source/Sources 406 Not Acceptable , E:Some index files failed to download. They have been ignored, or old ones used instead.
It seems to tell me my internet is not connected but it is at the time of the update.
Could anyone let me know what the problem is and where there might be a fix for it?
