Bluetooth toggle not working in Ubuntu 21.04

I updated my OS yesterday from 20.10 to 21.04. Everything was fine today until I tried to connect my Bluetooth earphones to my PC.

The Bluetooth service remains turned off even when I turn the toggle switch on.

Subsequently, it does not even scan for devices because, as expected, it is not switched on for the OS.

Is the issue common after this upgrade?

Please let me know if someone has a solution.

As you can see, Bluetooth is off, and it is not showing an option to switch it on.

And now even though I have switched it on, it is showing that it is off.

The issue is not only what the system shows.

It does not scan for devices.

Here:

In the second screenshot, I have switched on the toggle but it still does not scan for Bluetooth devices.

UPDATE AS OF 4th May, 2021:

1. I had reported the bug to Ubuntu. They have merged my report with an already existing bug report. If anyone wishes to follow it, here's the link: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926062

2. Someone on the launchpad site had pointed out in the comments that using the command systemctl restart bluetooth will turn on the Bluetooth from the terminal even if the toggle is not working. I believe this solution is working until Cannonical provides some fix updates.

Solution 1:

try:

sudo nano /etc/default/grub

substitute "quiet splash" by "quiet splash acpi_osi=Linux" save changes (nano only): CTRL+x / key y / Enter

sudo update-grub

restart computer.

Solution 2:

i had the very same problem on my Toshiba Satellite and it seems like Wayland is causing this just logout and choose Xorg login turn the airplane mode off and that's it Bluetooth an Wifi will work normal again after that you can logoff and chose Wayland if you prefer to I hope this will help you
