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

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

, etc.).

Run the following command to update the package index again:
sudo apt update
This time, you should see a successful update process!
