How To Update Gentoo

How To Articles

Updating Gentoo can sometimes be a daunting task, especially for those who are new to the world of Linux. However, with a little guidance, it can become a smooth and seamless process. In this article, I will share my personal experience and step-by-step instructions on how to update Gentoo.

Step 1: Preparing for the Update

Before diving into the update process, it’s crucial to ensure that your system is ready for it. Start by backing up all your important files and configurations. This step is essential as it provides a safety net in case anything goes wrong during the update.

Next, make sure you have a stable internet connection. A stable connection is important because it ensures a smooth download and installation process.

Step 2: Updating the Portage Tree

The Portage tree is what Gentoo uses to manage packages and software versions. To update the Portage tree, open the terminal and run the following command:

emerge --sync

This command updates the Portage tree by synchronizing it with the latest version available. It may take some time, depending on your internet connection speed.

Step 3: Updating the System

Once the Portage tree is updated, it’s time to update your system. To do this, run the following command:

emerge -avuDN --with-bdeps=y @world

This command tells Gentoo to update all the installed packages on your system. It will upgrade packages, install any missing dependencies, and remove any unnecessary packages. The -a flag asks for confirmation before making any changes, while the -v flag provides verbose output to keep you informed about the progress of the update.

Step 4: Cleaning Up

After the update is complete, it’s good practice to clean up any residual files or packages that are no longer needed. This helps to keep your system lean and efficient. Run the following commands:

emerge --depclean

The first command, emerge --depclean, removes any packages that are no longer required by your system. The second command, revdep-rebuild, checks for any broken dependencies and rebuilds them if necessary.

Step 5: Reboot

Finally, it’s time to reboot your system to ensure that all the updates take effect. Run the following command:


After the reboot, your Gentoo system should be up-to-date and ready to go!


Updating Gentoo may seem like a complex task, but with a little patience and attention to detail, it can be a smooth and rewarding experience. By following the steps outlined in this article, you can ensure that your Gentoo system remains secure, stable, and up-to-date.
