arduino.path instruction not working for Ubuntu

[n9iels]

The README of this plugin states the following about the arduino.path:

arduino.path - Path to Arduino, you can use a custom version of Arduino by modifying this setting to include the full path. Example: C:\Program Files\Arduino for Windows, /Applications for Mac, /home/$user/Downloads/arduino-1.8.1 for Linux. (Requires a restart after change). The default value is automatically detected from your Arduino IDE installation path.

I noticed that these instructions are not working for Ubuntu 18.04. For some reason, the $user (or $USER) variable is not used. The plugin keeps complaining about an invalid arduino.path till I changed this variable to my username. So the variable is not translated to the actual username.

@n9iels Thank you for your feedback, arduino.path doesn't expand variables now, we will update readme file later.

The arduino.path instruction has changed as bellow.
/home//Downloads/arduino-1.8.1 for Linux.

Just install:
sudo apt install python
pip install pyserial

everything works fine because arduino IDE works on python2.xx in ubuntu
