Can't turn on bluetooth on Ubuntu 18.04

Question

My Bluetooth suddenly stopped working in the middle of usage and I couldn't turn it on until I restarted my machine.

Bluetooth in the settings:

Bluetooth in the top bar:

Below is the output of my rfkill list:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no

I tried unblocking it from the command line using sudo rfkill unblock bluetooth and reinstalling the bluez package by running sudo apt install --reinstall bluez, but both methods did not work.

I just upgraded my machine to Ubuntu 18.04 from 16.04 and thought this problem would go away, but in fact it persists. Does anyone know how to fix it?

I have the same exact problem this morning. What was your solution? — Jeff, Mar 26 '19 at 13:23
@Jeff never found a solution. I tried googling and asking in the forum, but none helped — Hardian Lawi, Mar 27 '19 at 02:51
Try upgrading bluez as descibed here: https://askubuntu.com/questions/1036195/bluetooth-doesnt-work-after-resuming-from-sleep-ubuntu-18-04-lts — utapyngo, May 23 '19 at 04:41
We need further information. Please share the output of this first sudo systemctl status bluetooth.service. — Mr. Panda, Jul 18 '21 at 19:25

The only solution I found was

Reboot
Turn off the bluetooth in the BIOS
Exit
Get into the BIOS again and turn it on...

This is super tedious and I'm still looking for a workaround...

One thing that worked for me was to reload the btusb module, like this:

sudo modprobe -r btusb
sudo modprobe btusb

I did this on Debian 10, Ubuntu 18.04, Ubuntu 21.04, … It never ends.

I ran into the same problem and kept trying different solutions, until i saw a StackOverflow post stating to just:

Shutdown and Boot again

This fixed the problem with me.
