InstallationMedia issue

[Edson T. Marques]

Hello,
Is there any way that I can upgrade the definitions of origin of my installation? That is, today, when I see the error reports generated to send to the launchpad, I note that the item "InstallationMedia" is showing: "Ubuntu GNOME-4.15" Vivid Vervet "- Alpha amd64" ... It is possible to update these definitions?

Thank U!
