I have a Windows 8 and Ubuntu 13.04 dual boot. I want to update to 13.10, but when I try to do so the software updater says I have 12.10 installed and offers to install 13.04. I can't find a way of getting it to offer 13.10. If I say 'yes' to a 13.04 install (thinking, "oh well, it might actually offer me 13.10) of course it ceases the installation saying 'the software on this computer is up to date'.
I have another computer with a Vista/13.04 dual boot, and this gives the same problem. 'Settings' on both computers confirms 13.04 installed.
Could anyone shed any light on this please? I used the same ubuntu 13.04 installation disk for both installations; could there have been a problem with this?
