Linux updates: How to update Ubuntu

It should be noted that each Linux distro can be updated differently but we will focus on Ubuntu as it is the most used by users of this OS. We explain how to update Ubuntu, the different LTS versions that appear, the programs but also how to update the Ubuntu kernel.

Updates and versions

Linux updates to Ubuntu versions arrive every six months and LTS versions every two years, specifically in the spring of even years. The former offer us support for nine months and the latter offer us support for five years, which means that it will work correctly during this period and we will receive Linux updates without installing a new Ubuntu LTS version if you do not want. You won’t have a problem if you don’t.

Configure updates

To update or configure the update in Ubuntu, follow these steps:

  • Open Ubuntu desktop
  • Access the applications menu that you will find in it: touch the Win key on the keyboard
  • Type in the search engine: Software and updates

You will see that a pop-up window of the Ubuntu software opens in which we can access all the options, configure drivers, development, etc.

  • Go to the tab Updates in the top menu
  • You will see three options marked by default
    • Important security updates (eoan-security)
    • Recommended updates (eoan-updates)
    • Upgrades without technical support (eoan-backports)

They are all marked by default and will be installed as soon as they are detected. If they are not checked, check them. If you want them not to install, just remove the boxes. You’ll also find four drop-down menus with more options available:

  • Check equalizations automatically
  • When there are security updates
  • When there are other updates
  • Notify me of a new version of Ubuntu

Choose all the options that interest you: if you want it to be updated daily or weekly, if you want them to be downloaded and installed automatically or not, etc. Although by default they are searched daily, you can change this.

Update Linux - Ubuntu

Install Ubuntu patches and programs

You can update the applications you have with security patches or simply with new versions of them. You can do it from the Linux update center or from the Ubuntu terminal by executing commands.

From the update center you can go to:

  • Open the Ubuntu search engine
  • Write Software Update
  • Open the tool that appears on the screen
  • Automatically check for updates available
  • You will see if there is something available and its weight
  • Select what you want to update, uncheck what you don’t
  • Put in “Install Now” to confirm the process


Install latest version of Ubuntu

As we have explained in previous paragraphs, every six months there is a new version that is supported for nine months and every two years there is a more stable and durable LTS version, which is supported for five years.

You can download the Ubuntu versions from the update center

  • Open the Ubuntu search engine
  • Write software update
  • A pop-up window will appear: A new version is available
  • Click on the button “Yes, update now”
  • Wait for the process to complete
  • Restart the computer for the changes to complete
  • Start again and everything will be updated

From Terminal

There are several commands that you can use from Terminal for Linux updates:

  • To install new packages and patches: sudo apt update && sudo apt upgrade
  • To update the distro with new patches and packages: sudo apt update && sudo apt upgrade && sudo apt dist-upgrade
  • To install the latest version: sudo do-release-upgrade

Update the kernel

What is the kernel? If you have Linux, you will know what it is. Otherwise and in a nutshell, the kernel is the main core, in charge of everything working correctly. Therefore, we explain how to update the kernel in Ubuntu. It is not the only Linux distribution or distro but it is the most widely used. You can do it by hand but it is a tedious process and not recommended, unless you know how to do it and perfectly control the system, so there is another option is to resort to Ukuu (Ubuntu Kernel Update Utility), a tool to update the system kernel without complications, in a few clicks and for any user.

The first thing you should do is install it:

  • Open a terminal
  • Run the following:
    • sudo apt-add-repository –y ppa: teejee2008 / ppa
  • add it
  • Update the software repositories
  • Install with:
    • Sudo apt uptdate
    • Sudo apt install ukuu
  • Wait a few seconds and it will be installed

Once you have Ukuu installed, you can now update the Ubuntu kernel easily by running it, without complications as in the traditional way:

  • Type ukuu-gtk
  • A pop-up window will open with all versions
  • You will see which version is installed and which is the latest available
  • Tap on the “Settings” button
  • A new pop-up window will open to manage notifications
    • Notify when a new version is available
  • Check this option
  • Choose the version checking time: every how many hours you want it to be checked for something new and to notify you if it is
  • Select the version you want to install
  • Click on “Install”
  • It will start to download automatically
  • The process will take several minutes
  • Once finished, restart
  • Go back to the previous steps to check which version appears now

You will have already updated the Ubuntu Kernel easily with Ukuu.
