Ubuntu releases patches for the operating system regularly. Another positive of Ubuntu is that if a problem is found, it is fixed immediately so vulnerabilities will not be an issue with your computer. You should see a notification of updates when available, but you can certainly check manually to find any possible updates. Here’s how to update your Ubuntu computer manually.
Open the Terminal by clicking on “Applications” in the menu bar, hover over Accessories, and then click on “Terminal”
If you are familiar with Windows, the terminal in Ubuntu is exactly like the command prompt in Windows.
Once you have the terminal open, type:
sudo apt-get update
The word ‘sudo’ means you are running the command as root user so you will need to enter in your password when prompted.
Once all sources have been scanned, you will then see a notification icon in your menu bar if updates are available for installation and you can then install what is available for your computer’s setup.
You can run update as many times as you want to with no harm to your computer. Update away!
