Hi again.


Did Nik mean chmod o+w or chmod a+w? I looked to the manpage, a+w is
writeable for everyone. It can solve the message "failed to open
'/etc/tqt3/tqt_plugins_3.5rc.tmp'". But I learned that user shouldnt
write in /etc/... folder.

When I made chmod a+w /etc/tqt3 does it affect on /etc or only in
/etc/tqt3? I dont want to destroy my system. :/


For the new readers, this is my problem:

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?


I logged in today with the ubuntu standard desktop and the arduino ide
works great.


deloptes points in devel to $CLASSPATH, the var in empty in my shell.
./arduino is a bash script.


Thanks for the help.
