In this article, we will delve into the process of installing the latest package version using apt-get. apt-get is a powerful command-line tool used for handling packages in Linux distributions. It is especially useful when you want to automate the installation of software on your system.
To install the latest package version with apt-get, use the apt-get install <package-name> command. This will automatically install the latest version of the specified package from your repositories. If you want to install a specific version, you can use the syntax apt-get install <package-name>=<version>. Additionally, you can install packages from backport repositories using the -t <repository-name> flag.
Understanding apt-get
apt-get is part of the Advanced Packaging Tool (APT), which handles the management of software on Unix-like systems. It simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration, and installation of software packages, either from precompiled files or by compiling the source code.
Updating the Package List
Before you install the latest version of any package, it’s important to update your package list. This ensures that you have the most recent information about what packages are available and their versions. You can do this by running the following command:
apt-get updateThis command retrieves information about what packages can be installed, including what software they depend on, whether new versions of packages you already have installed are available, and so on.
Installing the Latest Package Version
To install the latest version of a package, you use the install command followed by the package name. Here’s the syntax:
apt-get install <package-name>For example, to install the latest version of Jenkins, you would run:
apt-get install jenkinsThis command will install the latest version of Jenkins available in your repositories.
Installing a Specific Version
If you want to install a specific version of a package, you can specify the version number. Here’s the syntax:
apt-get install <package-name>=<version>For example, to install Jenkins version 1.517, you would run:
apt-get install jenkins=1.517Installing from a Backport Repository
Sometimes, a more recent version of a package is available in a backport repository. These repositories are not installed by default. To install a package from a backport repository, you can use the -t flag followed by the repository name. Here’s the syntax:
apt-get -t <repository-name> install <package-name>For example, to install the latest version of golang from the xenial-backports repository, you would run:
apt-get -t xenial-backports install golangInstalling the Latest Version in a Script
If you need to install the latest version of a package using the apt-get command in a script or automation tool, you can use the -q -y --force-yes flags. These flags suppress the output (-q), automatically answer yes to prompts (-y), and force apt-get to proceed even if it would normally stop for user input (--force-yes). Here’s the syntax:
apt-get -q -y --force-yes install <package-name>=\*For example, to install the latest version of openjdk-6-jdk available in your repositories, you would run:
apt-get -q -y --force-yes install openjdk-6-jdk=\*Conclusion
In this article, we have covered how to install the latest package version using apt-get. We have also discussed how to install a specific version of a package, how to install a package from a backport repository, and how to install the latest version of a package in a script or automation tool. By understanding these concepts, you can effectively manage your software packages and ensure that you always have the latest versions installed.

Yes, you can install a specific version of a package by specifying the version number in the command. The syntax is apt-get install <package-name>=<version>. For example, to install Jenkins version 1.517, you would run apt-get install jenkins=1.517.
To install a package from a backport repository, you can use the command apt-get -t <repository-name> install <package-name>. You need to specify the repository name after the -t flag. For example, to install the latest version of golang from the xenial-backports repository, you would run apt-get -t xenial-backports install golang.
Yes, you can install the latest version of a package using apt-get in a script by using the flags -q -y --force-yes. These flags suppress the output (-q), automatically answer yes to prompts (-y), and force apt-get to proceed even if it would normally stop for user input (--force-yes). The syntax is apt-get -q -y --force-yes install <package-name>=\*. For example, to install the latest version of openjdk-6-jdk available in your repositories, you would run apt-get -q -y --force-yes install openjdk-6-jdk=\*.
