Java install RN214 OS 6.9.5

I am attempting to install Java to use the Unifi Controller. Whenever I try I get a bunch of dependancy errors. See below

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gcc-4.9-base : Breaks: gcc-4.9-base:armhf (!= 4.9.2-10+deb8u2) but 4.9.2-10+deb8u1 is to be installed

                 Depends: libx11-6 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
