I’ve connected RPi to TV to perform initial configuration as it doesn’t have ssh service enabled by default anymore.
I’ve selected Raspbian Stretch With Desktop as my OS for RPi. It seems the most popular OS for RPi and I have a previous experience with Ubuntu and they have a common parent Debian. It took significant amount of time to complete the install. Here is my current OS version.
pi@raspberrypi:~$ uname -a
Linux raspberrypi 4.19.34-v7+ #1211 SMP Mon Apr 8 22:56:37 BST 2019 armv7l GNU/Linux
