Tried installing netbeans and eclipse but both give the following errors (is this caused because the server is down and will be restored soon? I've not been able to use apt-get to install the missing packages either. Also tried http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html but it says that ls, mkdir etc are missing when it is not actually missing):
