Uninstall NFS Service

To uninstall NFS (Network File System) on Ubuntu, you need to remove the NFS server components and any associated configuration. Here’s how you can do it:

Uninstall NFS Server Components

1. Stop NFS Services: First, stop the NFS server services to prevent them from running:

   sudo systemctl stop nfs-server
   

2. Remove NFS Packages: Use apt to remove the NFS server packages. The specific package names might vary depending on your Ubuntu version and NFS setup. Typically, you may have packages like nfs-kernel-server:

   sudo apt purge nfs-kernel-server
   

3. Clean Up Configuration Files: After purging the packages, you can clean up any remaining configuration files:

   sudo apt autoremove
   

Uninstall NFS Client Components (Optional)

If you also want to remove NFS client components:

1. Stop NFS Client Services:

   sudo systemctl stop nfs-client.target
   

2. Remove NFS Client Packages: Again, the package names might vary, but typically it includes nfs-common:

   sudo apt purge nfs-common
   

3. Clean Up Configuration Files:

   sudo apt autoremove
   

Verify Removal

After performing the above steps, NFS should be uninstalled from your system. You can verify by checking if NFS-related services are stopped and if the packages are no longer installed:

sudo systemctl status nfs-server     # Check NFS server status (should show inactive or not found)
sudo systemctl status nfs-client     # Check NFS client status (if applicable)
dpkg -l | grep nfs                   # Check if NFS packages are listed (should be empty)

Additional Considerations

• Configuration Files: If you have customized configuration files (/etc/exports for NFS server or /etc/fstab for NFS mounts), you may want to manually remove or restore them as needed.
• Data and Shares: Uninstalling NFS does not delete any data stored on NFS shares. Ensure you have backed up any critical data before uninstalling if necessary.

By following these steps, you can uninstall NFS server and client components from your Ubuntu system effectively. Adjust the package names as needed based on your specific installation.
