I am running 13.04.
I opened Software Updater. It started OK and then came up with the following message: "Software updates are no longer provided for Ubuntu 13.04 " followed by "To stay secure, you should upgrade to Ubuntu 13.10"
Is this an error? What is happening?
Please can someone explain what is going on. I have never had this in any previous edition of Ubuntu and it has always been possible to run and update a system two releases back, let alone LTS versions.
