You need to search through the add programs or synaptic and find and install gdeb files, then you can right click on the zipped file, select open with gdeb, then click on the install box at the bottom of the window. You will have to enter your admin password. It will probably say that the install failed, but it will install. You need to have Java installed first, which you can also find in the add programs. Limewire will then work but the problem I am experiencing is that the limewire.deb package is reported as broken because it is looking for PDK Java 7, and then the add programs will not work. You have to use synaptic to uninstall limewire, then everything works again. Pain in the ass to have to install and uninstall Limewire each time you want to use it. If anyone knows a fix, I'd appreciate it.
