Question

How do I check the version of Raspian I currently have installed? I would imagine that it is Stretch but would like to verify that.

Answer 1

You can install lsb_release if you don't have it and run:

lsb_release -a

if you are looking for kernel info:

 uname -a

or you can do this:

cat /etc/os-release
