How to fix a broken package in Ubuntu?

Below are the Steps that will show you how to troubleshoot and repair broken packages on Ubuntu using the available APT and DPKG tools.

Step 1: Check for Updates

Starting the troubleshooting requires rebuilding the dependency list of all packages. Giving APT the –fix-missing option permits it to ignore any missing packages. By using this option, one is sure that the process of updating software will be complete without generating or showing any disturbance of pop-up error messages from APT.

Command:

sudo apt update --fix-missing

Output:

Fixing the missing Dependencies

Step 2: Force APT to Correct Missing Dependencies or Broken Packages

Unavailability of required package dependencies is a common reason for software packages errors.

Use apt install with the -f flag to tell Advanced Packaging Tool to find out any missing packages and auto-fetching them and putting them in place.

Command:

sudo apt install -f

Output:

Installing the Unavailable Packages

Step 3: Force Reconfigure or Remove Broken Packages with DPKG

Corrupted packages can sometimes create issues with the proper functioning of the base package management application.

This command re-calibrates DPKG, the basic software responsible for installing and manipulating packages.

Command:

sudo dpkg --configure -a

Output:

Re-Configure the DPKG,

Check whether DPKG has identified any packages that need to be reinstalled.

Command:

sudo dpkg -l | grep ^..R

Output:

List all the Broken Packages

For example, if one or more affected packages are displayed by the above command, you can try removing them by typing below Command, In my case i have every Package that’s why it’s showing nothing in your it will display some Packages name you just Put the name of the Package with the Below Command.

Command:

sudo dpkg --purge --force-all [package-name]

Step 4: Resolve DPKG Lock Issue

While trying to install or modify a package, the DPKG lock error crops up because of another process that is currently accessing the DPKG package management system. However, this error sometimes occurs when no other processes are interacting with DPKG in a competitive manner.

To solve this problem, manually delete the lock file :

Command:

sudo rm /var/lib/apt/lists/lock

Output:

Remove the Lock file

Additionally, remove the redundant lock on the package cache directory:

Command:

sudo rm /var/cache/apt/archives/lock

Output:

Remove the Redundant lock File

Deleting these lock files allows DPKG and APT wrapper back into action without complaining about locked or unavailable package system thus making it possible to install, upgrade or configure software at ease. It is highly probable that an earlier operation on a package failed to release its lock thereby blocking any subsequent actions. Rubbing off these locking files gives a simple solution for smooth sailing through packaging management.

Step 5: Update the System

After, Following the all above Steps you need to Reinstall all the Lock files and update the System for that you need to use the Following Command. This Command will Update the Whole System and Install all the package & Dependencies on the System.

Command:

sudo apt update

Output:

Update the System

Conclusion

To begin with, package issues encountered in Ubuntu might feel hard to handle, but the solutions are easy to understand for any user. These few commands will be enough for you to be able to address software management problems on your Ubuntu system. Even beginners in terms of package management will know how to deal with these simple terminal commands so as to get broken packages or updates back working again.
