When Chromebooks first started supporting Android apps, there was some confusion about exactly which Chromebooks were supposed to support. The same thing begins to play, but to a lesser extent, with support for Linux apps.
You have always been able to install Linux applications (or other Linux-based operating systems) on Chromebooks through a solution called Crouton because Chrome OS is based on the Linux kernel. The new method of installing Linux apps is much easier than before because it is an integral part of the operating system.
But not all Chromebooks receive official support for Linux apps.

The new method of installing Linux apps on a Chromebook (internally known as Crostini) is based on changes introduced in version 3.14 of the Linux kernel. When a Chromebook is developed, its firmware is written around a specific version of the Linux kernel. The main reason for this is stability; Keeping the kernel version locked makes it easier for Google to update Chromebooks without compromising performance. A Chromebook works just as well in year five as it does on day one.
The significant change in core 3.14 is better virtualization support. This means that the app is running in a sandbox, so a bad process in an app does not crash your entire system. This also makes the Crostini method safer, which is a major sales point behind Chromebooks.
Some models may not have hardware support for many Linux applications. A large part of that list contains Chromebooks that use 32-bit ARM processors, while most desktop Linux devices are written for 64-bit X86 platforms.
Many of the unsupported Chromebook models also come close to the end of guaranteed software updates. Chromebook still does everything it does today, but it's not meaningful from Google's perspective to spend time and money adding new features to a device that will not be supported much anymore anyway.
What Chromebooks Won

How to view Chromebook hard disk specification cations and system informationApps on your Chromebook, you can still use the older install method known as Crouton. This works on any Chromebook, regardless of the processor or Linux kernel version. If you simply want to switch back and forth between your Linux apps and web-based tools, you can run a Linux desktop in a single browser tab. If you prefer each app has its own window so it feels more built-in you can also do it.
If you really want to experiment, you can also install another Linux-based operating system like Ubuntu. If you've had your Chromebook for a long time, it's not a bad idea to investigate this in advance for when Google stops sending security updates to your device. Because Chrome OS is based on Linux, you should not have any problems with display or audio drivers that prevent you from using the device.
Or you can continue to use your Chromebook as it is. You will not lose any features that you have come to rely on, so if you have already learned how to be productive with web-based tools, you can continue.
