So, you have setup your Raspberry Pi and installed the official Raspbian OS on it. Though you felt it running smoothly and having no issues, you should update it at regular times whenever the official upgraded version launches. Here, I will step-by-step guide you on quickly updating your official Raspberry Pi Operating System.
How to Update Raspbian OS
Step-1: First of all, you need to get the software package names as Advanced Packaging Tool (APT). It’s a Debian based way to install, upgrade, remove, and manage the software. It works on the ARM architecture of Raspberry Pi.
Step-2: Now, open the command terminal on your Raspberry Pi desktop and write the following, then click enter:
sudo apt-get update
Step-3: It is the time to upgrade the installed packages now. Enter the following commands one by one.
sudo apt-get upgrade
sudo apt-get dist–upgrade
Step-4: You can also update the Firmware and Kernel to get the latest version to experiment on your Raspberry Pi projects. Enter the commands below:
sudo apt-get install rpi-update
Note: if you don’t need the advanced Firmware version, then don’t do this fourth step.
Step-5: When you download and install the package updates, check the capacity of data storage on your Raspberry Pi SD card. You will need to check it manually by running the commands:
If you find that there is a lack space on the SD card to store the newly downloaded data, then you can remove the unnecessary files in the archives. Enter the command below:
sudo apt-get clean
Upgrade the Raspbian OS Regularly
Updating the official Raspberry Pi Operating System with the latest Jessie Version is easy and quick. Only a couple of commands you need to enter, and your system will be ready with the latest packages.
The Raspberry Pi Foundation occasionally make changes in the Raspbian Image which includes the upgradation in the compatible software packages too. So, to enjoy with your Raspberry Pi board with all the latest and advanced features, you should check and update its OS at regular times.
