I confirm this issue is happening on a clean Arch install, even after installing bluez, the files required by the service are not there.

----------------------

Update:

A workaround is to downgrade to the previous version:

sudo pacman -U https://archive.archlinux.org/packages/b/bluez/bluez-5.63-2-x86_64.pkg.tar.zst https://archive.archlinux.org/packages/b/bluez-utils/bluez-utils-5.63-2-x86_64.pkg.tar.zst


Then try starting the bluetooth service again, and it should work:

systemctl start bluetooth.service


After that, if the bluez is updated again to the latest version, it will still keep working.

Upstream bluez has added a `ReadWritePaths=/var/lib/bluetooth` to its `bluetooth.service`, which failed to start because `/var/lib/bluetooth` is missing in package.

So another workaround is simply creating the dir manually with `sudo install -m 700 -d /var/lib/bluetooth`, and restart the service.

The downgrade approach works because bluetoothd would create `/var/lib/bluetooth` on startup.
