How to install latest Arduino IDE? [duplicate]

As we know Arduino has non-official Snap which can access serial ports only if installed as classic (but not indicated in snap find output):

$ snap find arduino
Name Version Developer Notes Summary
arduino-mhall119 1.8.5 mhall119 - Arduino IDE

Arduino packages from repositories are outdated:

Package arduino

trusty (14.04LTS) (electronics): AVR development board IDE and built-in libraries [universe]
1:1.0.5+dfsg2-2: all
xenial (16.04LTS) (electronics): AVR development board IDE and built-in libraries [universe]
2:1.0.5+dfsg2-4: all
artful (electronics): AVR development board IDE and built-in libraries [universe]
2:1.0.5+dfsg2-4.1: all
bionic (electronics): AVR development board IDE and built-in libraries [universe]
2:1.0.5+dfsg2-4.1: all

According to official Arduino site the latest version of Arduino IDE is 1.8.9.

One can download IDE from official site, extract and install it with install.sh. Then when newer version will be released repeat this action. But it looks difficult and not user-friendly.

How can I get latest Arduino IDE installed in user-friendly way?

Arduino IDE is installable with Ubuntu Make:

Install Ubuntu Make
- for Ubuntu 16.04 LTS from official PPA ppa:lyzardking/ubuntu-make:
```
sudo add-apt-repository ppa:lyzardking/ubuntu-make
sudo apt-get update
sudo apt-get install ubuntu-make
```
  PPA is needed because of two fact: package for 16.04 LTS does not support installation of Arduino.
Note: umake from 18.04 Universe repo may fail installing arduino ide. If so, you will need to purge ubuntu-make and install from the PPA. If this is the case you will also need to delete ~/.local/share/umake with rm -rf ~/.local/share/umake. See this QA for more info.
- for Ubuntu 18.04 LTS and newer systems from universe repository:
```
sudo apt-get update
sudo apt-get install ubuntu-make
```
Install Arduino IDE with Ubuntu Make
```
umake electronics arduino
```
or for 18.04 (without PPA, may fail)
```
umake ide arduino
```
This will download Arduino IDE from official site and install it to ~/.local/share/umake/ide/arduino and set corresponding shortcuts and file associations for it.
You can repeat this command again to get newer version.

Note: do not forget to add your user to dialout group with sudo usermod -a -G dialout $USER .

The easiest way to install the latest Arduino IDE is to use the arduino snap:

snap install arduino

Then add your user to the dailout group:

sudo usermod -a -G dialout $USER

After this, reboot your device and open Arduino IDE.

A note about Python support

The Arduino IDE snap runs inside of a sandbox for security and stability reasons. This means it cannot access the Python libraries on your device. The snap bundles Python 3 and the serial library. If you need any other Python dependencies, you can install them inside of the sandbox using the arduino.pip command.
