Raspberry Pi 4

Debian 10 Buster got released a while back and this means it should be possible to upgrade Raspbian OS on Rasberry Pi devices to the Raspbian Buster as well. Raspbian OS is based on Debian as you remember.

Step 1: Confirm Your Current Linux Kernel and OS release

Always a good step: confirm Raspbian version and check your current Linux Kernel version:

greys@s7:~ $ uname -a
Linux s7 4.19.42-v7+ #1219 SMP Tue May 14 21:20:58 BST 2019 armv7l GNU/Linux
greys@s7:~ $ cat /etc/debian_version
9.9

Step 2: Update Existing Release Before Upgrading to the Next

Just like in the upgrade Jessie to Stretch procedure, we start with using apt-get command to upgrade existing packages available for the current release.

The reason it's recommended to do this is by moving to the latest available version in your current release you are minimising the changes required for the upgrade to the next release. Changes and configuration file syntax are not likely to be as dramatic between last version in current release and first version in the next release.

We refresh list of available updates:

greys@s7:~ $ sudo apt-get update

and install these updates:

Run apt-get dist-upgrade too, in my case it shows zero packages:

Step 3: Upgrade Raspbian OS to Buster

Three elements to this step:

1. Update release code name in /etc/apt/sources.list
2. Download list of available package updates
3. Upgrade Raspbian OS

Update release name in /etc/apt/sources.list

First, let's edit /etc/apt/sources.list file:

greys@s7:~ $ sudo vi /etc/apt/sources.list

I changed this:

to this:

Refresh packages info with apt-get update

Now we can refresh information about available package updates:

greys@s7:~ $ sudo apt-get update

And, finally, we're ready to…

Upgrade Raspbian packages to Buster release

greys@s7:~ $ sudo apt-get upgrade
Reading package lists… Done
Building dependency tree
Reading state information… Done

… and finish it off with apt dist-upgrade:

greys@s7:~ $ sudo apt-get dist-upgrade

After this operation, 1,045 MB of additional disk space will be used.
Do you want to continue? [Y/n]

Step 4: Confirm Successful Upgrade

We need to reboot the Raspberry Pi now:

greys@s7:~ $ sudo shutdown -r now

…and run uname -a command and inspect the /etc/debian_version file to confirm that our Raspberry Pi is indeed running the latest version of Raspbian OS now:
