Where Is The List Of Manually Installed Packages On Debian?

Introduction

As a Debian user, you may have encountered a situation where you need to identify the manually installed packages on your system. However, when you check the file /var/lib/apt/extended_states, you may be surprised to find that every package listed shows Auto-Installed: 1. This can be confusing, especially if you manually installed some packages. In this article, we will explore where the list of manually installed packages on Debian is located and how to identify them.

Understanding Auto-Installed Packages

Before we dive into the solution, let's understand what Auto-Installed means in the context of Debian. When you install a package using the apt package manager, it can be either manually installed or automatically installed. Manually installed packages are those that you have explicitly installed using the apt command, while automatically installed packages are those that are installed as dependencies of other packages.

In Debian, the apt package manager uses a file called /var/lib/apt/extended_states to keep track of the installation status of packages. This file contains information about each package, including whether it was installed manually or automatically.

The Problem with /var/lib/apt/extended_states

As you mentioned, when you check the file /var/lib/apt/extended_states, you may find that every package listed shows Auto-Installed: 1. This can be misleading, especially if you manually installed some packages. The reason for this is that the apt package manager considers all packages that are installed as dependencies of other packages to be automatically installed, even if you manually installed them.

Where are Manually Installed Packages Listed?

So, where are manually installed packages listed in Debian? The answer is that they are not listed in the /var/lib/apt/extended_states file. Instead, manually installed packages are listed in the /var/lib/dpkg/available file.

Understanding the /var/lib/dpkg/available File

The /var/lib/dpkg/available file contains a list of all packages that are available for installation on your system. This file is used by the dpkg package manager to keep track of the installation status of packages.

When you manually install a package using the apt command, the dpkg package manager updates the /var/lib/dpkg/available file to reflect the new installation. The file contains information about each package, including whether it was installed manually or automatically.

How to Identify Manually Installed Packages

To identify manually installed packages on your Debian system, you can use the following command:

dpkg -l | grep ^ii

This command will list all packages that are installed on your system, including manually installed packages. The ^ii pattern matches the first two characters of the package status, which indicates that the package is installed.

Alternatively, you can use the following command to list only manually installed packages:

dpkg -l | grep ^ii | grep -v ^ii-autom

This command will list only packages that are installed manually, excluding packages that are installed automatically.

Conclusion In conclusion, manually installed packages on Debian are not listed in the /var/lib/apt/extended_states file. Instead, they are listed in the /var/lib/dpkg/available file. To identify manually installed packages, you can use the dpkg package manager and the commands listed above.

Additional Tips and Tricks

• To list all packages that are installed manually, you can use the following command:

dpkg -l | grep ^ii | grep -v ^ii-autom | grep -v ^ii-*

This command will list only packages that are installed manually, excluding packages that are installed automatically or as dependencies of other packages.

• To list all packages that are installed automatically, you can use the following command:

dpkg -l | grep ^ii-autom

This command will list only packages that are installed automatically.

• To list all packages that are installed as dependencies of other packages, you can use the following command:

dpkg -l | grep ^ii-* | grep -v ^ii-autom

This command will list only packages that are installed as dependencies of other packages.
