I am quite new with Ubuntu and I am using PhpStorm for writing code.
Can you please tell me how to update it from 2017.3.4 to 2018.1 without losing setup?
the latest official version of phpstorm is Version 2017.3.6.
Version 2018 is only a preview. You can download the preview here: https://www.jetbrains.com/phpstorm/download/download-thanks.html?type=eap&platform=linux
