Ubuntu 20.04 bluetooth not working
I've installed Ubuntu 20.04 and bluetooth is not working for me. But it works in a live session if I boot that from USB. Can anyone help me please?
systemctl | grep -i blue output:

I experienced the same issue, after a hot boot switch from Windows to Ubuntu, Bluetooth failed to work. I followed the Ubuntu bug report here, and Bluetooth fully functions. Use the following commands:
sudo rmmod btusbsudo modprobe btusb
I have the same problem with bluetooth with ubuntu 20.04, and fixed by this way
sudo apt install blueman
sudo add-apt-repository ppa:blaze/rtbth-dkms
sudo apt-get update
sudo apt-get install rtbth-dkms
sudo vim /etc/modules
Comment all and add this line
rtbth
Reboot and open
sudo blueman-manager
If still not work, try this
sudo rmmod btusb
sleep 1
sudo modprobe btusb
If still not work, try this
update /etc/default/grub with this value
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nommconf pcie_aspm=off"
update grub
sudo update-grub
then reboot and enjoy your music
