Correct ia32-libs install (Ubuntu 10.04)

I try to run LAMPP on my AMD64 and got next message:

“XAMPP is currently only availably as 32 bit application. Please use a 32 bit compatibility library”.

But ia32-libs was currently installed. In google I was find many tips like "install getlibs-all", and something like "reboot after install, install it with sudo, etc", sure, it didn't work. But here I was find good advice how to make ia32-libs correctly working:

sudo gedit /etc/apt/sources.list

uncomment all the lines “thats what i did because i am lame”, and

sudo apt-get update

sudo apt-get install ia32-libs

and now all work fine.
