inspiron 14z & problems with upgrading ubuntu 11.04 to 11.10
Hello,
I'm trying to upgrade Ubuntu 11.04 (x64) on my new Dell Inspiron 14z. In Update Manager window I can see: "new Ubuntu 11.10 release is available". After pressing the button [Upgrade] the following dialog with error will be displayed:
Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server.
What's wrong and how I can fix it?
Thank you!
PS
In the tab "Other Software" there are 2 dell lines:

Okey, It's my brute-force solution for the problem:
After all I got 11.10 x64 on Inspiron 14z. At the first look, everything is all right (all devices work properly).
But under 11.04 battery lifetime was approximately 6-7 hours (in light usage-mode - web-serfing via wifi). Under 11.10 -- life-time dramatically decreased to 3-4 hours. I don't know which kind of magic has been used during preparation of 11.04-build in Dell, but I want the same thing under 11.10 :) Can anybody from Dell help me?
Thank you in advance!
