How to update Linux and its applications [A]

Before you now start installing the KDE Discover you should take a look at my post about activating Linux and the first steps after that. Especially the check for available updates, and their installation should be done as always before installing a new application. Here again, the necessary commands for doing this:

sudo apt-get update && sudo apt-get upgrade

How to start the installation of KDE Discover [A]

Then we can start! With the following command, you can install the KDE Discover on your Chrome OS device:

sudo apt install plasma-discover

If you are sure, you must confirm this with “y” again:

The installation can take quite a while. So just be patient and watch the system’s progress bar or just keep surfing the internet:

Once the installation is complete, your screen should look something like the following screenshot:

Then I would recommend that you restart your Chrome OS device once. When this is done, you should be able to start the KDE Discover just like any other app on your system:

Clicking on the area marked red in the screenshot opens the information page of the application found by the search. From there you can start the installation of the application by clicking on the “Install” button:

A progress bar then appears in the information page of the application:

Depending on the application and, of course, the performance of your Chrome OS device, the installation can take a few minutes, an hour, or even longer. If the installation of the application is now complete, you can start it from the information page with the “Launch” button or (possibly only after a restart and starting the terminal or another Linux application) just like any other app:

Back to KDE Discover: As described here in the post, you can now install and use numerous applications without a Linux terminal and cryptic commands with just one click!
