MySQL won't start because of AppArmor

AppArmor is a Linux security module that provides mandatory access control (MAC) for programs. It works by enforcing security policies that restrict how applications interact with the system, helping to protect against potential vulnerabilities and malicious behavior. Each application is assigned a security profile that specifies which files, network resources, and other system resources it can access.

MySQL Workbench when installed as a Snap package on Ubuntu, it operates under the confinement of AppArmor. This confinement can sometimes block necessary services and interactions, leading to issues such as inability to connect to MySQL or errors related to authentication.

Solution

Connect Required Snap Interfaces

Snap applications, like MySQL Workbench, operate within a confined environment and often require additional permissions to function correctly. To resolve access issues, you may need to connect specific Snap interfaces. Open your terminal and run the following commands:

snap connect mysql-workbench-community:password-manager-service
snap connect mysql-workbench-community:ssh-keys
snap connect mysql-workbench-community:cups-control

Enter fullscreen mode Exit fullscreen mode

These commands grant MySQL Workbench the necessary permissions to interact with services such as password management, SSH keys, and printing controls.

Conclusion

By connecting the necessary Snap interfaces you can resolve common access issues with MySQL Workbench on Ubuntu. These steps should help you restore full functionality and ensure smooth operation of your database management tasks.
