How to fix broken update error in linux (Terminal)

Linux is a robust operating system, but occasionally you might encounter a 'broken update error' when trying to update your system through the terminal. This issue can halt your system updates and potentially affect system stability. Here’s a comprehensive guide on how to resolve this error, ensuring your Linux system remains up-to-date and secure.

Understanding the Error

A broken update error in Linux typically occurs when package dependencies are unsatisfied, when there are conflicts between packages, or when the package repositories are not correctly configured. This can lead to a partial or failed update, rendering your system's package manager unable to proceed with updates.

Step 1: Check Internet Connection

Before proceeding, ensure your internet connection is stable. An interrupted or weak connection can cause update processes to fail. Use ping command to check your connectivity, for example:


Step 2: Update Repository Lists

Start by refreshing your repository lists. This ensures that your package manager has the latest information about available packages and their dependencies:

sudo apt-get update

For non-Debian based distributions, replace apt-get with the package manager relevant to your distribution (like yum for Fedora or pacman for Arch Linux).

Step 3: Upgrade Packages

Attempt to upgrade all your system packages with:

sudo apt-get upgrade

This might resolve dependency issues that were causing the update process to break.

Step 4: Fix Broken Packages

If the upgrade doesn’t resolve the issue, you can specifically target and fix broken packages:

sudo apt-get install -f

The -f flag stands for “fix broken”. It repairs broken dependencies, helping the package manager to recover.

Step 5: Clean Up

Clear out the local repository of retrieved package files. It's a good practice to clean up the cache to free space and remove potentially corrupted files:

sudo apt-get clean

Step 6: Remove Unnecessary Packages

Remove packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed:

sudo apt-get autoremove

Step 7: Configure Package Manager

If the error persists, reconfigure the package manager. This can help resolve any corrupt configurations:

sudo dpkg --configure -a

Step 8: Manually Resolve Dependencies

Sometimes, you may need to manually fix dependencies. Look at the error messages carefully. They often indicate which package is causing the problem. You can then either remove, reinstall, or update that specific package.

Step 9: Check for Repository Issues

Ensure that your system’s repositories are correctly set up. Incorrect or outdated sources can cause update errors. The repository configuration files are typically located in /etc/apt/sources.list and /etc/apt/sources.list.d/. Make sure they contain the correct URLs and distribution names.

Step 10: Seek Community Support

If you’ve tried all the above and still face issues, seek support from the Linux community. Linux has a vibrant community on forums like Ask Ubuntu, Linux Mint forums, or Fedora forums, depending on your distribution.

If the method above has not made any changes and is still experiencing errors, try the method below:

Step 1: Identify and Stop the Conflicting Process

You can find out what process is holding the lock by using the process ID (PID) given in the error message. In your case, the PID is 1582.


ps -f -p 1582
in the terminal to see details about the process.

If it's a process that can be safely stopped, use

sudo kill -9 1582
Be cautious with this command, as killing essential system processes can cause problems.

Step 2: Remove the Lock Files

If you are certain no other apt processes are running, you can manually remove the lock files.


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

Additionally, you might need to remove the lock file in the cache directory:

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

And the lock file in the dpkg directory:

sudo rm /var/lib/dpkg/lock

Note: This is generally not recommended unless you're sure that no apt processes are running, as it can potentially corrupt your package database.

Step 4 : Restart your computer


Resolving broken update errors in Linux involves a systematic approach to identify and fix package dependencies, configuration issues, and repository errors. By following these steps, most update issues can be resolved directly from the terminal, restoring the smooth functioning of your Linux system. Remember, regular updates are crucial for security and stability, so resolving these errors promptly is important.
