Systemd не удается запустить цель bluetooth?

когда я запускаю свою систему (ОС Debian), и systemd достигает целевого Bluetooth, требуется 1min30s прежде чем сообщить мне, что зависимость не удалась для disk_by_device и для swap.

пожалуйста, как можно отключить bluetooth определенно ?

iamatacos@debian1:~ $ sudo journalctl -u bluetooth
