How to Fix: Linux/Bluez: Bluetooth keyboard cannot be added, getting strange "file not found" error from bluetoothd

A Bluetooth keyboard user is experiencing issues with pairing their device after a recent Arch Linux update. The keyboard was previously paired using the GNOME GUI, but it can no longer be added to the system. When scanning for devices, the keyboard appears briefly before disappearing. The user has tried pairing from the command line using bluetoothctl without success.

This issue can be frustrating for users who rely on Bluetooth keyboards for daily tasks. In this guide, we will walk you through the steps to troubleshoot and potentially resolve the problem.

⚠️ Common Causes

• The 'security block' error is likely caused by a mismatch between the keyboard's security settings and those configured on the system. This can occur when the keyboard was previously paired using a GUI, but the system configuration has been updated. To resolve this issue, you may need to reset the keyboard's security settings or update the system configuration to match the keyboard's settings.
• Another possible cause of the 'No such file or directory' error is that the bluetoothd service is not properly configured to handle input devices. This can occur when the system configuration has been updated, causing the bluetoothd service to lose track of the keyboard device.

🔧 Proven Troubleshooting Steps

✨ Wrapping Up

If you have followed these steps and still experience issues with pairing your Bluetooth keyboard, it may be necessary to seek further assistance from Arch Linux support or a professional IT technician. However, by resetting the keyboard's security settings or updating the system configuration and bluetoothd service, you should be able to resolve the issue and get your keyboard working again.
