install Postman

1. download Postman native app from here
2. unzip it

# unzip to home directory with privilege update problem
$ tar -xzf Postman.x.y.tar.gz -C ~

3. create a desktop file named Postman.desktop

# create this file
$ touch ~/.local/share/applications/Postman.desktop
# copy stuff below into it

[Desktop Entry]
Encoding=UTF-8
Name=Postman
Exec=/home/chong/Postman/app/Postman %U
Icon=/home/chong/Postman/app/resources/app/assets/icon.png
Terminal=false
Type=Application
Categories=Development;

Since I installed at /home/chong directory, so you gotta replace my home directory/home/chong with your_postman_install_dir

4. launch the app
   open the Postman directory, double click Postman executable file. And Lock to Launcher

Note: Since I didn't install this app at /opt directory, so I can update or upgrade smoothly with any privilege problem.
