Token Posted April 2, 2016 Share Posted April 2, 2016 (edited) the latest grabbed from the ubunutu software center also im on java 6 but also have java 7 installed running precise 12.04 Having java x installed is different from using java x to run programs. OSBot requires java 8 in order to run, and as far as I know, all linux distributions have java 7 preinstalled. After installing java 8 you have make it uses that one generally through "alternatives --config java" command.
