No bluetooth adapter found (Ubuntu 18.04 with ubuntu mate)


#1

Hello,
I am dsperately trying to get bluetooth running.
I have uninstalled and reinstalled blueman and blueman-gnome, bluez:armhf, bluez-tools - nothing worked.

When I tried to manage bluetooth via terminal, I failed. Can anybody help, please??

Here are some results of the checks I performed

bluetoothctl show says No default controler available.

hcitool doesn’t find any devices
