I installed Arduino IDE in two different ways (only god knows why). The first one was via using of manager
apt-get and other was manually via downloading, unzipping and installation through the
It seems that on Ubuntu 14.04 the
sudo apt-get install arduino
command provides an installation of an old version of Arduino IDE.
So eventually I was launching Arduino IDE by
arduino command in my terminal (actually I was using d-menu in i3). No surprise it ran the old one installed by
apt-get. I just removed that version by
sudo apt-get remove arduino
And now I am using executable
arduino inside unzipped folder. Actually, I am not using Arduino IDE explicitly at all. I am using a Makefile from here.
