Uninstall Grafana on Ubuntu 20.04: A Clean Sweep Guide
Grafana is a fantastic open-source platform for visualizing and analyzing time series data. But sometimes, you might need to remove it from your Ubuntu 20.0.4 system. Whether you’re switching to a different monitoring tool, troubleshooting an issue, or simply freeing up disk space, a clean uninstallation is crucial. This comprehensive guide will walk you through the process step-by-step, ensuring you completely remove Grafana and its associated files.
Understanding the Uninstall Process
Before diving into the commands, let’s understand the different stages involved in uninstalling Grafana:
- Stopping the Service: It’s essential to stop the Grafana service before proceeding. This prevents any data corruption or unexpected behavior during the removal process.
- Package Removal: We’ll use the
aptpackage manager, the standard tool for managing software packages on Ubuntu, to remove the Grafana package itself. - Dependency Removal (Optional): By default,
aptremoves any unused dependencies installed alongside Grafana. However, if you want to be extra thorough, you can explicitly remove them. - Repository Removal (Optional): If you added a dedicated Grafana repository during installation, it’s wise to remove it to avoid conflicts with future package management operations.
- Configuration and Data Removal (Optional): By default, package removal doesn’t touch configuration files or data folders. If you want to completely eliminate any trace of Grafana, you’ll need to remove these manually.
Important Note: Throughout this guide, we’ll use the sudo command to execute tasks with administrative privileges. Make sure you enter your password when prompted.

These are typically located in:

rm -rfcommand to delete these directories. However, be very careful with this command, as it permanently deletes files and folders.
Verification and Conclusion

This command should return a message indicating that the service is not found or inactive.
By following these steps, you can effectively uninstall Grafana and ensure a clean system. Remember to adjust the commands based on your specific installation method (e.g., repository vs. package file) and exercise caution when manually deleting configuration files and data folders.
