We can now run Linux apps on our Chromebook using the Linux Development Environment (LDE). But we still need to keep those apps up to date. So, in this video, we’ll show you how to update all the apps you’ve installed using Flatpak.
Just a heads up, while ChromeOS will automatically update itself, the Linux version built into LDE isn’t. So, even though LDE is separate from ChromeOS, we still need to keep both operating systems up to date with security patches and bug fixes.
Flatpak is a super useful tool we use to install Linux apps. It’s like a one-stop shop for updating all our installed apps. However while Linux is usually less likely to get malware and viruses compared to other operating systems. It’s still a good idea to keep your Chromebook apps up to date to stay safe.
- Open the Linux Development Environment menu.
- From within the menu select Penguin to open a Linux Terminal windows.
- First we are going to check for update by typing:
sudo apt update
- Once the check has been completed, we next need to perform any updates that Linux has found. To do this we simply type the following:
sudo apt-get dist-upgrade
- As applications install via Flatpak have not been updated. We can use the following command to see which applications need updating:
flatpak list
- We now need to update all applications that were installed using Flatpak:
sudo flatpak update
- Flatpak will now install any updates for our applications.
- When we are once again presented with the command prompt we can close the terminal window, and use our Linux applications.
- To close the terminal window simply typing:
exit
- When you press enter on the keyboard you will be returned to the LDE menu.
Note: Sometimes things can go wrong and you are presented with a “no remote refs found similar to flathub” error message. Based on the error message, the instance of Linux cannot find the Flathub repository for the package we are looking to download. So we need to use a specific command that will instruct Linux to repair the Flathub link.
