I don't know why three lines were added and only one is "nightly".
There was no upp installed prior to this after installing 10.04
Then in Synaptic selected upp, whatever was automatically marked with that was downloaded.
This was the same with two notebooks, installed 10.04 under Win XP and Vista.
I did not do any make, make install as I read nothing that said this was necessary when using PPA.
I don't do much installing in Linux except follow instructions so it may be my error.
Just a download and run to install like it is done under Win, is that something that would be near impossible under Ubuntu?
