So this is basically a combination of this and this:
sudo apt-get purge scala sudo apt-get autoremove cd ~/desktop/scala wget http://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.tgz tar xzf scala-2.11.8.tgz sudo mv scala-2.11.8 /usr/share/scala sudo ln -s /usr/share/scala/bin/scala /usr/bin/scala sudo ln -s /usr/share/scala/bin/scalac /usr/bin/scalac sudo ln -s /usr/share/scala/bin/fsc /usr/bin/fsc sudo ln -s /usr/share/scala/bin/sbaz /usr/bin/sbaz sudo ln -s /usr/share/scala/bin/sbaz-setup /usr/bin/sbaz-setup sudo ln -s /usr/share/scala/bin/scaladoc /usr/bin/scaladoc sudo ln -s /usr/share/scala/bin/scalap /usr/bin/scalap
Everything is easy when you know how!
