after installation of ubuntu 20.04 on my old asus (x550vb) laptop my bluetooth is not working. I have dualboot with windows and bluetooth is working fine there. What I found that bluetooth package http://ppa.launchpad.net/bluetooth/bluez/ubuntu is not available for ubuntu focal. I tried to switch to apt bionic packages but it doesn't seems to work.
sudo /etc/init.d/bluetooth status
● bluetooth.service - Bluetooth service

Active: inactive (dead)
Docs: man:bluetoothd(8)
Jan 06 15:36:02 guliver-X550VB systemd[1]: Condition check resulted in Bluetooth service being skipped.
When I try to restart bluetooth service it shows status OK but not every time. Sometimes this doesn't happen and it remain inactive.
dmesg | grep -i blue

It also seems that Bluetooth is not found with command below. I don't understand why.
sudo rfkill list

Hard blocked: no
I found solutions that include installing blueman but the installation is failing. I also tried to install python3.7 (also python3.6) and change system python priority to older version with command sudo update-alternatives --config python3 but this didn't help.
apt-get install blueman
The following packages have unmet dependencies:
blueman : Depends: python3 (< 3.7) but 3.8.2-0ubuntu2 is to be installed
E: Unable to correct problems, you have held broken packages.
What could solve this problem? Cheers!

I managed to install blueman (thanks for the suggestion). But bluetooth still does not work due to "No adapter found/missing". I tried to enable bluetooth manager but it fails, see logs below. Also bluetooth service daemon is running without any errors.
