Introduction

As a Linux user, you may have encountered situations where you accidentally installed packages meant for a different distribution. This can lead to a mess in your package manager, making it difficult to install or update packages. In this article, we will discuss how to fix the apt package manager after accidentally installing Arch essential packages on a system running a different distribution, such as Pop_OS!.

Understanding the Problem

During the installation of Arch Linux, you followed the manual and accidentally mounted the wrong root partition. You have Pop_OS! installed on a second drive, and you mounted its root partition in step 1.11. This mistake led to the installation of Arch essential packages on your Pop_OS! system. Now, you are facing issues with the apt package manager, and you need to fix it.

Why Arch Essential Packages Cause Issues

Arch Linux and Pop_OS! are two different distributions with different package managers. Arch Linux uses pacman as its package manager, while Pop_OS! uses apt. When you installed Arch essential packages on your Pop_OS! system, it caused conflicts with the apt package manager. The Arch essential packages are designed to work with pacman, not apt. This incompatibility leads to issues with package installation, updates, and removal.

Symptoms of the Problem

If you have accidentally installed Arch essential packages on your Pop_OS! system, you may experience the following symptoms:

Package installation issues: You may encounter errors when trying to install packages using apt.
Package update issues: You may face issues when trying to update packages using apt.
Package removal issues: You may encounter errors when trying to remove packages using apt.

Fixing apt after Accidentally Installing Arch Essential Packages

To fix the apt package manager after accidentally installing Arch essential packages, follow these steps:

Step 1: Identify and Remove Arch Essential Packages

First, you need to identify the Arch essential packages installed on your system. You can use the following command to list all installed packages:

dpkg --list

This command will list all installed packages on your system. Look for packages with names starting with arch- or linux-. These are likely to be Arch essential packages.

Once you have identified the packages, you can remove them using the following command:

sudo apt remove <package_name>

Replace <package_name> with the actual name of the package you want to remove.

Step 2: Purge Arch Essential Packages

After removing the packages, you need to purge them to remove any remaining configuration files. You can use the following command to purge packages:

sudo apt purge <package_name>

Again, replace <package_name> with the actual name of the package you want to purge.

Step 3: Clean apt Cache

After removing and purging packages, you need to clean the apt cache to remove any remaining package information. You can use the following command to clean the cache:

sudo apt clean

Step 4: Update apt Package List

After cleaning the cache, you need to update the apt package list to reflect the changes. You can use the following command to update the package list:

sudo apt update

Step 5: Install apt Package Manager

If the apt package manager is still not working correctly, you may need to reinstall it. You can use the following command to reinstall apt:

sudo apt install apt

Step 6: Reconfigure apt

After reinstalling apt, you need to reconfigure it to reflect the changes. You can use the following command to reconfigure apt:

sudo dpkg --configure -a

Step 7: Verify apt Installation

Finally, you need to verify that apt is working correctly. You can use the following command to verify installation:

sudo apt install <package_name>

Replace <package_name> with the actual name of a package you want to install. If apt is working correctly, the package should be installed successfully.
