Linux LXDE updates

hi,

I'm still a newbie with Linux and the DE1-Soc. I'm running the "normal" version of Linux/LXDE: Linaro 13.04, quantal, Linux 3.12

The first problem is one I already solved: had to update /etc/apt/sources.list from

ports.ubunto.com/ubuntu-ports/ quantal main universe

to

old-releases.ubuntu.com/Ubuntu/ quantal main universe

Running the normal "apt-get update" fixed the immediate issue. Now I am attempting to load several PPAs, but am somewhat stumped by the "missing" add-apt-repository command by:# apt-get install add-apt-repository

I get the error of "Unable to locate package add-apt-repository

Since the only way I know how to add a PPA is add-apt-repository, I am somewhat stuck. I see Linaro Maintainers overlay ppa at: ppa:linaro-maintainers/overlay but cannot figure out how to install it.

Many thanks!

Steve
