How to upgrade Raspberry Pi OS

This article is intended to look at the commands needed for the Raspberry Pi Upgradation to Latest Version.

I have a RPi 5 running Raspberry Pi OS Lite (Bookworm), and I  upgrade it to the newest Raspberry OS (Debian 13 Trixie).

Upgrade Raspberry Pi OS from Bookworm to Trixie.

 

Check Raspberry OS Version (Current)

cat /etc/os-release

output

cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"

VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

 

Make Sure the System Is Up to Date

Before upgrading, update and upgrade all existing packages,Ensure your current system is fully updated.Perform a full upgrade of your existing OS installation.

sudo apt update
sudo apt full-upgrade
sudo reboot
