As a new operating system is launched, an expectation is created that it has been added, improved or eliminated at both the development and administrative levels . In the case of Linux distributions, with each update drastic changes are executed, always focused on guaranteeing the total integrity of the user at the level of applications, processes and services..
Debian has just released version 9.4 which has some changes compared to its predecessor and today in TechnoWikis we will see what changes it includes and how we can upgrade to this new version in a simple way.

Now, let's see how to upgrade to this new version of Debian..
2. How to check the current Debian version and update the system
Step 1
The first step to take is to validate which version of Debian 9 we currently have, for this we execute the following:
lsb_release -a join me -mrs
We can validate that we have Debian version 9.1.
Step 2
Now, the next step will be to update the Debian 9 packages by running the following line:
apt-get update
Step 3
Then we execute the following:
apt-get dist-upgrade
There we enter the letter S to proceed to download all the updates for Debian where the update to version 9.4 is included.
Step 4
Once this process is finished we proceed to restart the system by executing:
reboot
Finally, when the system is loaded again we will execute the following:
join me -mrs lsb_release -a w
We can validate that the system has been updated to Debian version 9.4. It's that simple to upgrade to this new version of this great Linux distribution.
