Here’s how to upgrade Debian 8 Jessie to Debian 9 Stretch in a quick and easy way.
Steps to upgrade Debian 8 Jessie to Debian 9 Stretch
The first thing to have is the latest version of Debian (currently in version 8.8 ). After which you should open a terminal window and write the following:
Sudo apt-get update
Sudo apt-get upgrade Sudo apt-get dist-upgrade
After doing this, you will have to update the software repositories of the distribution. For which you would have to write the following in the terminal:
Sudo nano /etc/apt/sources.list
Writing the above, the Nano text editor will open along with the sources.List file with the Debian repositories. In this case, you must change the text of the lines where the word “Jessie” appears. And replace it with the word “Stretch”. After this, you have to save the changes by pressing the Control + O key and then push the Control + X combination to exit.
Finally, you will have to repeat the first step, opening a terminal window and typing again the following:
Sudo apt-get update
Sudo apt-get upgrade
Sudo apt-get dist-upgrade
After doing this, the process of upgrading from Debian 8 to the new Debian 9 version will begin.
An alternative to this method would be the use of a Debian 9 Stretch ISO image from the debian.org web portal.
Also, there are also Debian 9 Stretch ISO images with the GNOME, KDE, Xfce, LXDE, Cinnamon and MATE desktop environments.
