Using just the text would be great since that way it can be searched and indexed later.
What I would do to find out why this happens:
The service seems to fail on a nonexistant directory.
When I try to navigate there by hand it does not exist on my system
/sys/class $ cd bluetooth ✔
cd: no such file or directory: bluetooth
(I presume it does not on your system, it would be good to check)
The /sys/ folder is something special (more on this here )
The source of the skip could be that the device is not recognized for some reason and thus not present in the /sys/class/bluetooth folder (I have no BT device so for me it is empty) This is my guess at the moment.
A device that is not recognosed could be a hardware issue, a kernel issue, config issue. Providing the info in the linked post (how to request support) specifically the text output of
inxi -Fazy General system information
journalctl --boot --priority=3 the boot log of the current session with just errors of your machine.
btw: Thanks for testing, it helps everyone and it is appreciated.
