Introduction

This article introduces how to install software on Ubuntu using apt-get.

install software

update list first

sudo apt-get update

install software 

sudo apt-get install <package name>[=<version>]

The version can be omitted, and the latest version is the default.

Example (install docker-compose-plugin)

Install the latest version:

sudo apt-get install docker-compose-plugin

Install the specified version:

sudo apt-get install docker-compose-plugin=2.12.2~ubuntu-focal

Check software version

        You cannot list all supported versions by using the following command, because each version is related to the system version and CPU architecture. For example, a software that supports Ubuntu system 16.04 with a CPU architecture of amd64 is only 1.0 and 1.2, and the rest are not supported. , so there are only two types of enumeration.

Method 1: apt-cache madison

sudo apt-cache madison <package name>

example

Law 2: apt policy

sudo apt-cache policy <package name>

example

Install offline

method

    vi /etc/apt/sources.list
          add a local path, such as: deb file:/work apt_packages/

    sudo apt-get update

    sudo apt-get install <package name>
