Problem with starting arduino ide

Hi, I have ubuntu 18.4 with trinity R14.0.5. If I want to start the arduino ide from arduino.cc (download and extract arduino-1.8.7-linux64.tar.xz) there comes the splash-screen for one second and it crashes with this message: ~/arduino-1.8.7$ ./arduino Picked up JAVA_TOOL_OPTIONS: TQSettings::sync: failed to open '/etc/tqt3/tqt_plugins_3.5rc.tmp' for writing What I have to install or change? Thank you very much for the great Desktop.
