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.
