How to Build Debian 9 Stretch to Debian 10.1 Buster
One of the most important steps you should take before upgrading your Debian system to a new version is Backup. Because you don’t want to lose the settings and configurations of the programs or software you use on your computer.
For example, if you use Debian Linux as a web server, it is useful to back up the settings of some software such as MySQL, PHP. Because the versions of the programs that you use during the upgrade will also be upgraded, you should make backups.
We recommend that you use TimeShift snapshot for backup before updating your Debian computer. You can simulate the TimeShift application to the System Restore service in Windows.
Before upgrading to Debian 10, you must configure your Debian 9 Stretch system’s Repository addresses for Buster.
Right-click on the desktop, open Terminal, and execute the following command to change the Debian Repository addresses.
sudo sed –i ‘s/stretch/buster/g’ /etc/apt/sources.list
The above command will replace all Stretch records in the repository list with Buster. After applying it, execute the following cat /etc/apt/sources.list command in Terminal to check for changes.
After editing the repository file, execute the sudo apt-get update command to perform an index refresh for the currently installed applications on your Linux system.
sudo apt-get update
Execute sudo apt-get upgrade to install new updates for your Debian system.
sudo apt-get upgrade
After running the upgrade command, press Y to confirm the use of additional disk space, and then press Enter.
During the upgrade, press Enter to read the comments created on the terminal. Otherwise, you can press Q (q) to exit directly.
When the Package Configuration window opens, press Enter on the Yes option to confirm starting the MiniSSDP Daemon service automatically.
Select the interface to be listened to in the Configuring minissdpd window and press Enter on OK.
In the question window of Restart services during package upgrades without asking, proceed with Yes by pressing Enter.
In this step, execute the sudo apt-get dist-upgrade command in Terminal to upgrade your old Debian 9 version to the 10 new version.
sudo apt-get dist-upgrade
Press Y and then Enter to confirm disk usage for the full update.
The update process may take some time, depending on the hardware performance of your computer and the speed of your Internet connection. When all packages are downloaded and installed over the Internet, your Linux computer will be upgraded to the new version.
After changing the system version, restart your computer, and then run the cat /etc/os-release command on the terminal to check for the new version.
In addition, you can check the version from the System Info.
