Apple bluetooth keyboard-device added successfully but failed to connect


Up until this morning I had my Apple bluetooth keyboard auto connecting when I boot up. Now, for some strange reason (an update?, though don't recall updating anything) it doesn't auto connect, and when I try and manually connect I get the following error message

Code:
Device added successfully but failed to connect
Running latest ubuntu-mate 16.04. Can anyone suggest troubleshooting steps?

I wonder if it's a problem with pairing. When you try and manually connect, do you get to where a pairing number is given?

Might have duplicated your problem. On my Mint 18 Mate I disconnected the Apple keyboard, and the bluetooth settings software seemed to freeze. I could not disconnect the remaining mouse nor the speaker, and could not reconnect the keyboard. This persisted after killing and restarting the bluetooth settings, and even after a complete reboot of the computer. Interestingly, the bluetooth settings listed my computer's name incorrectly as "Bastien's Computer".

I opened a terminal window and ran as regular user:
$ rfkill list
Code:
0: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
4: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no
Then:
$ rfkill unblock 4
Code:
0: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
4: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
And the bluetooth settings went back to normal and I was able to reconnect the keyboard. The secret was getting rid of that softblocked hci0.

Hope this works for you!

This may seem insulting, but, are you sure the keyboard is charged?

IME, sometimes the whole bluetooth stack needs restarting. The easiest way to do that is a reboot.
