What Are Broken Packages in Ubuntu and How Do They Occur?
Broken packages can be considered in Ubuntu when they haven’t installed properly, been updated, or set up correctly. Such mistakes could occur from broken installs, conflicts of dependency issues or even the package database can be corrupted. The possible issues created by such issues are malfunctioning of some software, system crashes, and the inability to upgrade or install other packages.
How Broken Packages Occur on Ubuntu:
Interrupted Installations or Updates: A package’s installation may be interrupted due to a power failure, network failure, or cancellation through any user interface. At times, this can leave the package partially installed, rendering it broken, as that installation cannot function correctly before its completion.
Dependency Conflicts: Most packages in Ubuntu depend on other packages or certain versions of other packages. If the dependencies for any package are not installed properly or updated, dependency problems occur, thus rendering a package broken. For instance, a package could necessitate a version of another package that is not installed or outdated, making the package unusable.
Corrupt package database: The package database, which manages the installation of the software on your system, can sometimes go bad and result in broken or missing packages. It could happen due to improper shutdowns, hard disk errors, or filesystem problems.

Incorrect Package Removal or Purging: Sometimes, users may attempt to manually remove or purge packages using apt-get or dpkg commands without fully understanding the dependencies. This could accidentally remove critical packages or parts of other installed software, leading to broken functionality.
Package version inconsistency: Installing third-party sources or using packages not from the official Ubuntu source could sometimes lead to package conflicts. This is because some of those packages might not be perfectly compatible with other packages or specific versions of libraries may not be available, hence making the packages broken.
How to Find Broken Packages in Ubuntu
Here’s how you can find broken packages on your system before “Ubuntu fix broken packages”:
1. Using the dpkg Command:
The dpkg tool can help detect partial or broken installations of packages. Run the following command in your terminal:
This command will search for any packages that are not configured properly and list them. It will highlight packages that are only partially installed or are in a broken state.
This tells you that the package name was unpacked but wasn’t configured correctly, which is a sign of a broken package.
2. Checking APT Logs for Broken Packages:
APT logs keep track of every installation, removal, and upgrade. You can scan for entries related to broken packages using the following command:
This will highlight where there have been instances that had broken packages causing a failure in the installation during some past updates or package operations.
3. Using apt-get check:
The apt-get check command checks for any dependency and package errors that have broken dependencies. It does not correct them but rather points out the issue:
This will check for any un-resolvable package dependencies and errors and show you the broken packages that need attention.
4. Verifying Installed Packages with dpkg -l:
You can also list all the packages installed and look for ones that are not properly installed or configured. Type in:
This will show you all the packages that are broken. The output displays the packages that are not marked ii; thus, they are probably being installed or are broken.
5. Using Synaptic Package Manager
If you rather like having a graphical frontend to manage your packages Synaptic package manager makes broken packages pretty easy to locate.
- Launch Synaptic: Look for it in your Application Menu Open Custom Filters > Broken.
- This filter will list all the packages that are broken or missing dependencies.
- Synaptic allows you to quickly reinstall or remove broken packages through its graphical interface.
How To Fix Broken Package in Ubuntu: 5 Methods
Here we will discuss five methods for “Ubuntu fix broken packages”, with detailed explanations and real output examples for each.
1. Using apt-get to Fix Broken Packages
This is the first method for “Ubuntu fix broken packages”. apt-get is one of the most reliable and common tools for managing packages in Ubuntu. The tool can automatically handle broken packages, resolve dependencies, and fix other package-related issues.
Steps:
First update the package list by running:
Then use the following command to try to repair broken packages:
The -f (or –fix-broken) option instructs apt-get to try to fix any broken dependencies.
Explanation:
When you run sudo apt-get install -f on Ubuntu, it will scan the system for missing dependencies or packages that were not properly installed. It then attempts to fix those by downloading and installing the appropriate versions or completing unfinished installations.

2. Using dpkg to Reconfigure and Resolve Packages
The second method for “Ubuntu fix broken packages” is dpkg. dpkg refers to a low-level package manager that deals with the installation of packages and their configurations. If the case comes to broken packages, it may help reconfigure partially installed packages.

Output:
3. Using apt-get dist-upgrade to solve dependency problems
Sometimes packages are broken due to the dependency problem that prevents them from upgrading. The reason why the dist-upgrade command is useful is that, in addition to upgrading, it also solves any dependencies or conflicts.
Steps:
First, update your entire system
Then run this command to upgrade your package more comprehensively:
The dist-upgrade command upgrades more than a regular upgrade. It tries to correct broken packages by installing or removing additional dependencies. This is very useful when a package’s dependencies have changed or are no longer compatible with the system.
4. Using Synaptic Package Manager (Graphical Method)
The fourth method for “Ubuntu fix broken packages” is using the synaptic package manager. If you would rather use a graphical tool, Synaptic Package Manager is a great way to find and repair broken packages. Synaptic is a graphical application for managing software and for fixing broken packages without a terminal.
Steps
- Launch Synaptic Package Manager using your application menu. End.
- In Synaptic, go to Custom Filters > Broken. A list of packages with broken dependencies will appear.
- Highlight broken package(s) and then mark for reinstallation or mark for removal – or you can try and upgrade or downgrade the package accordingly.
- Once you have clicked on the packages you will be using, click apply to fix the broken package(s).
Explanation
Synaptic is able to manage packages more intuitively, with reinstall, remove, or upgrade options to solve the problems. It automatically identifies broken dependencies and gives recommendations.
Example Output
After the changes are applied, Synaptic may output a message like this:
5. Manual Uninstall and Reinstall of Package

This procedure ensures that the package is completely removed before reinstalling it, which may remove problems due to corrupted installation.
Steps:
First of all, uninstall the broken package using the following command:
After uninstalling the package, clean up the system to remove any remaining configuration files:
Finally, reinstall the package:
Explanation
This method completely removes the package, including its configuration files, and then reinstalls it. This approach is useful when there are deep-rooted issues with the package installation, such as corrupted files or incorrect configurations.
