When I installed Limewire a couple of months ago I remember having a problem with the installation script.

Try the "Other" section in Limewire and download a Linux version without the installer script. Here is the link:

To install it manually do these commands:

mkdir limewire
cd limewire
tar -xzf ../LimeWireLinux.tgz

To run Limewire do this:

./runLime.sh
