There's your answer, it should be in the repos. Limewire however, is very easy to install with Alien, its just not necessary.

IGF

root@3[home]# alien -d LimeWireLinux.rpm
File "LimeWireLinux.rpm" not found.

i also cant install java. im sorry if im really annoying, i just want my computer to run and im still learning. i started from basicly knowing nothing.

The Ubuntu Wiki has an article that will tell you all about how to install Java:
https://help.ubuntu.com/community/Java
As for Frostwire/Limewire/Anything else, I suggest you read this article:
How to install anything in Ubuntu
I know those say 'Ubuntu' but it should easily transfer to MEPIS. The only thing to note is that MEPIS may or may not use something other than Synaptic.

I highly recommend against trying to install the .rpm when you can just as easily get Frostwire/Limewire from the website or from the MEPIS repositories. It's built for Redhat-based systems, and could either not work or break your system.

if it can break my system why would i want to use it? thanks for the links btw

another thing, how do you find respitories? in synaptic i searched java nothing came up, but when i searched java-gcj-compat it came up.

this is what comes up when i try to install frostwire in kpackage or dpkg or whatever:
<n/Desktop/frostwire-4.13.1.5-1.i586.deb' ;echo RESULT=$?

Starting FrostWire...

OOPS, you don't seem to have a valid JRE. FrostWire works best with Sun JRE available at http://www.java.com
OOPS, unable to locate java exec in /usr/lib/ hierarchy
You need to upgrade to JRE 1.5.x or newer from http://www.java.com

OOPS, unable to locate java exec in /usr/java/ hierarchy

ls: /opt/j*: No such file or directory
OOPS, unable to locate java exec in /opt/ hierarchy
You need to upgrade to JRE 1.5.x or newer from http://www.java.com

Exactly, that's what I was saying. You want to use that as a last resort because it can be problematic.

Anyway, you've got Frostwire installed properly, but not the Java Runtime Environment. Do me a favor: in the console, type 'cat /etc/apt/sources.list' and paste the output here. And in the meantime, search for 'sun-java'.
