First list the currently installed kernels

Dpkg-- get-selections | grep linux

For example, to uninstall linux5.1.9, execute the command:

Sudo apt remove-- purge linux-headers-5.1.9-050109

In addition to linux-header, you also need to uninstall linux-modules and linux-image-unsigned

Command:

Sudo apt remove-- purge linux-modules-5.1.9-050109-generic

This uninstalls the 5.1.9 kernel.

Deepin

Deep operating system is an open source GNU/Linux operating system based on Linux kernel and mainly based on desktop applications, which supports laptops, desktops and all-in-one computers. Deep operating system (deepin) includes deep desktop environment (DDE) and nearly 30 deep original applications, as well as several applications from the open source community to support the daily study and work of the majority of users. In addition, through the deep store, you can also get support for nearly a thousand applications to meet your extended operating system needs. The deep operating system is jointly built by the professional operating system research and development team and the deep technology community. Its name comes from the deep technology community name "deepin", which means the profound pursuit and exploration of life and the future.

Deep operating system (deepin) is the first Linux distribution with international influence in China. As of July 25, 2019, Deep operating system supports 33 languages and has users on six continents except Antarctica. Deep Desktop Environment (deepinDDE) and a large number of applications have been transplanted to more than a dozen international Linux distributions and communities, including Fedora, Ubuntu, Arch and so on. Deepin has long been among the top 10 in the world on the open source operating system statistics website DistroWatch.

Linux

Linux, whose full name is GNU/Linux, is a set of Unix-like operating system that is free to use and spread freely. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and Unix. With the development of the Internet, Linux has received support from software enthusiasts, organizations and companies all over the world. In addition to maintaining a strong momentum of development in servers, it has made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve Linux according to their own needs to maximize meet the needs of users.

Shell is the user interface of the system, which provides an interface for users to interact with the kernel. It receives the command entered by the user and sends it to the kernel for execution.

Advantages of Linux:

Stability and efficiency: because Linux is developed from Unix, Linux and Unix have many similarities, not only in the user interface and mode of operation, Linux also inherits the excellent stability and efficiency of Unix. For servers using Linux as the operating system, it is quite common to run without downtime for a year.

Low configuration requirements: Linux has very low hardware requirements, and it can run smoothly on computers a few years ago. With Windows, you need to constantly upgrade the machine's hardware.

Free or small fee: Linux is based on GPL, so anyone can use or modify the original code for free. It costs a little bit of money only if you choose a distribution of Linux made by some vendors.

Strong support: a large number of Linux enthusiasts will communicate and discuss, and develop and share some good software, with a very open atmosphere for use.

Security: Linux has considerable user and community support, so it can quickly discover system vulnerabilities and quickly release security patches.

These are the details of how Linux deepin uninstalls unused old kernels. Please pay more attention to other related articles!
