Unable to locate package mysql-server

The error message "Unable to locate package mysql-server" usually indicates that the package manager (such as apt) cannot find the MySQL Server package in its repository. This can happen if the package name is incorrect or if the repository is not properly configured.

To resolve this issue, you can try the following steps:

1. Update the package lists by running the command:

   sudo apt update

2. Double-check the package name to ensure it is correct. The correct package name for MySQL Server on Ubuntu is usually "mysql-server" or "mysql-server-<version>". For example, for MySQL Server 8.0, you would use "mysql-server-8.0".

3. If you are using a specific version of Ubuntu, make sure that the repository for that version is enabled. Some repositories may not be enabled by default. You can check the enabled repositories in the "/etc/apt/sources.list" file.

4. If the package still cannot be found, it is possible that the repository you are using does not have the MySQL Server package. In this case, you may need to add a different repository that provides the package, or manually install MySQL Server from another source.

Remember to run the commands with sudo privileges to ensure proper access to system resources.
