I am trying to install SW4STM32 on Ubuntu 20.04 LTS. I have downloaded the file for installation and done all the changes for execution on the system. But on the website, it is mentioned that to install SW4STM32, we need JRE and gksudo is required but unfortunately gksudo is deprecated from Ubuntu now. So, how to install this software on the Ubuntu 20.04 machine. Please suggest a way for that.
