Did you select the option to upgrade to 11.10 rather than update packages for 11.04? <div class="gmail_quote">On 11 Nov 2011 14:27, "Norman Silverstone" <<a href="mailto:norman@littletank.org">norman@littletank.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I am using Ubuntu 11.04 and, today, ran Update Manager. The usual window appeared with a list of updates and I selected install updates. I entered my password and a small window appeared which,amongst other things, said what looked like Downloaded 0 B of 1 B. After a little while, another window appeared and I was asked to insert a CD/DVD'Ubuntu 11.10_Oneiric Ocelot_-Release i386 (20111012)' and given the choice to Cancel or Continue. As I have no idea what this is all about I chose Cancel and the window for Update Manager re-appeared with the list of packages to be installed and any attempt to install updates starts the cycle over again. Could someone please tell me what I need to do to be able to install the updates.
