How to install Appium-Desktop on Ubuntu16

Can you give me a step by step on how to install the Appium- Desktop on Ubuntu16.

Currently I have Appium installed and can start it from the terminal and automate Android.
But now I want the GUI version, in order to do iOS, as I cannot find any info on how to do this, other than using the Appium-Desktop.
On Git, there is a .exe (Windows), .dmg (Mac), so I downloaded the Source tar.gz from
and extracted it, but I don’t know how to install and start it! The gives me no info to do this.

Can you please help? I am new to this… Many thanks in advance,

Looks like the latest beta release (1.2.0-beta.3) does not have an AppImage binary. You should use the one from 1.2.0-beta.2:

Please see this for more info:

Yes I saw this, The person who replied said he provided Appium 1.0.0 - beta.
I could not find it!

I don’t understand. You can’t use 1.2.0-beta.2? Can you explain that?

Sorry, I made a mistake.
Your solution worked for me! Thank you!
