upgraded to 12.04 a box with a bunch of blank rectangles...

Update Manager>click 'Settings' in the bottom left corner>find the Lucid repositories>untick.

That will help. If you have done an upgrade from 10.04/11.10 then you probably have some residual repos still enabled. These kind of upgrades can be problematic and a clean install is generally better (good reason to keep your data on a separate /home partition or similar setup to your OS).

bucky-
I went to settings, but couldn't find lucid repositories?...

ok, i found it by going to dash home typing in "update" which gave me the folder "update manager" i clicked it and went to "settings" then "other software" and the only thing checked is
"canonical partners added by software center
sofware packaged by canonical for their partners"

Don't sweat the window of squares. It's supposed to be a warning message of some sort. You can either ignore them, or click the lower right rectangle. In English language installs, those 2 squares spell "NO". (I suppose in French it has three squares and in German four

Same thing happened to me on upgrade from 10.04 to 12.04.

I copied the boxes to the clipboard and quickly opened a text editor. When pasted the message appeared.

An error occurred while loading or saving
configuration info for evolution-alarm-notify.
Some of your configuration settings may

That's this bug:

It would be nice to get more people to click on "effects me too" to turn up the bug heat

ok, so maybe that was it.

the thing is, and i really have no idea what i'm doing with this computer stuff, during the installation i think i clicked "no" to something about removing old packages. I'm wondering if I have a bunch of old packages in here now from 10.04 that I don't need.

Also, when i go to shut down now, I get a black screen with a bunch of writing on it, that I didn't get before. Also, it takes longer for the boot up and shutdown now.???

that might be trivial, you are now using unity, it must use more resources than your previous system.
