I can across a reference (see below) to PPA while looking for a fix to my wireless problem. And I would like to know what it is. I don't have any references to ppa.launchpad in ''/etc/apt/sources.list'', which doesn't surprise me as, although my Dell 1525 is less than 6 months old, I live in a country where Dell doesn't support linux (I am running Ubuntu).

So, I was wondering what PPA is and is it something I want to install.

How do I find out about it?

Cheers,

'''Description:'''  Update Dell's PPA (Personal Package Archives) entry in ''/etc/apt/sources.list'' from Ubuntu 7.10 to 8.04.

'''Systems Affected:''' Inspiron E1505n, 1420n, 1525n, 530n and XPS M1330n.

'''Impact:''' So you can download Dell's custom packages needed for drivers and other updates for Ubuntu 8.04.

'''Fix:''' In ''/etc/apt/sources.list''. Change PPA entry from

 deb http://ppa.launchpad.net/dell-team/ubuntu gutsy main
 deb-src http://ppa.launchpad.net/dell-team/ubuntu gutsy main

to

 deb http://ppa.launchpad.net/dell-team/ubuntu hardy main
 deb-src http://ppa.launchpad.net/dell-team/ubuntu hardy main

Finally, update packages:

 $ sudo apt-get update
 $ sudo apt-get upgrade
