How to Fix APT Update After Upgrading the MySQL.list File?

If you’ve recently upgraded your MySQL.list file and found yourself stuck with an error message when running the apt update command, you’re not alone! Many users have encountered this issue, and in this article, we’ll guide you through a step-by-step process to resolve the problem and get your system running smoothly again.

What Causes the Issue?

When you upgrade the MySQL.list file, it can sometimes cause conflicts with the package manager, leading to errors when running the apt update command. This is because the MySQL.list file contains repository information that’s essential for the package manager to function correctly. If the file is modified or corrupted, it can prevent the package manager from updating correctly.

Symptoms of the Issue

If you’re experiencing this issue, you may see error messages like:

E: The repository ‘http://repo.mysql.com/apt/ubuntu focal InRelease’ is not signed.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

or

E: Failed to fetch http://repo.mysql.com/apt/ubuntu/dists/focal/InRelease  Could not resolve ‘repo.mysql.com’
E: The repository ‘http://repo.mysql.com/apt/ubuntu focal InRelease’ is not signed.

Step-by-Step Solution

DON’T PANIC! We’ve got you covered. Follow these steps to fix the issue and get your system running smoothly again:

Step 1: Remove the MySQL.list File

First, let’s remove the MySQL.list file to start fresh. Run the following command:

sudo rm /etc/apt/sources.list.d/mysql.list

Step 2: Update the Package Index

Next, update the package index to ensure that the package manager is aware of the changes:

sudo apt update

You may still see error messages at this stage, but don’t worry, we’re getting closer to a solution!

Step 3: Re-add the MySQL Repository

Now, let’s re-add the MySQL repository using the following command:

sudo add-apt-repository ‘deb http://repo.mysql.com/apt/ubuntu/ focal mysql-8.0’

Replace focal with your Ubuntu version (e.g., bionic, xenial, etc.).

Step 4: Update the Package Index Again

Run the following command to update the package index again:

sudo apt update

This time, you should see a successful update process!

Step 5: Verify the Fix

Finally, let’s verify that the issue is resolved by running the following command:

sudo apt full-upgrade

If everything is working correctly, you should see a successful upgrade process. If you still encounter issues, you can try running sudo apt autoclean and sudo apt autoremove to clean up any remaining issues.
