Thanks for your help with this so far... i've tried the command, here is the result... /home/user # dpkg -r libgles1 dpkg: dependency problems prevent removal of libgles1: teeworlds depends on libgles1; however: Package libgles1 is to be removed. dpkg: error processing libgles1 (--remove): dependency problems - not removing Errors were encountered while processing: libgles1 -- If it helps, i do have an application called teeworlds installed?
