I wanted to upgrade to 13.04 and as a necessity I need to update to 12.10. I have successfully updated in the past from Ubuntu 10 to Ubuntu 11 ans 12.04. Somehow, when I try from terminal or from update manager the update fails with shown in the following error.
I have also submitted the bug report via launchpad. I don't wish to update using dvd to save applications. Any alternative?
