Title:
Bluetooth will not stay on or connect to devices when on

Bug description:
Since upgrading from Ubuntu 20.10, my internal bluetooth card as well
as an external usb dongle will not work. Bluetooth starts as off, and
cannot be turned on. If I use systemctl to turn it on, it is on but
doesn't find any devices through bluez. Blueman finds devices but
cannot connect to them. The hardware on this machine has remained
identical; the only difference is the new version of Ubuntu. Hence
the problem has to be software.
