Ubuntu not updating correctly - Failed to download packages check internet connection

[Sinfieldd]

Hi,

I'm having an issue with Ubuntu 12.04 at the moment whereby it takes a while to log in because it is opening update manager (96 updates) and when I try to update it, I am greeted with the message 'Failed to download packages' and 'check your internet connection'.

I am definitely connected to the internet, as I am posting this now.

I've posted the details below:

Failed to fetch http://gb.archive.ubuntu.com/ubuntu/...0.14_amd64.deb 404 Not Found [IP: 194.169.254.10 80]

Does anybody know what the remedy for this is?

Many thanks.

Can you post your sources list.
From a terminal.
cat /etc/apt/sources.list

]Ok. From terminal again

sudo apt-get update && sudo apt-get upgrade

Post back any errors.

It seemed to work from terminal, the only thing I could pick out as an error was this:

W: You may want to run apt-get update to correct these problems


I would run sudo apt-get update again but it would just show the same thing once it was done.

Funnily enough it's working on update manager now..

[philinux]

Yes you have a duplicate for the cdrom. I would remove one from software sources.
