Upgrading any Distro version in debian
Upgrading distribution versions is one of the most frustruating jobs, expecially when there’s no GUI interface that can upgrade everything with just a click of button. But once you start being a professional personnal working in the industry, you need to learn how to upgrade from one version of a distribution to the latest one so as to keep the system secure.
In this blog, I will be going through, how you can upgrade Debian to the latest stable version.
Currently I was having Debian 9(Stretch), which I installed a long time ago. I use Debian with i3WM and it’s the lightest OS I came across after Arch linux. Later I discovered that the distribution version that I was running was outdated and it’s time for an upgrade. Hence I decided to do so.
Find about the versions from Debian’s official release page
