title: "Systemd-Resolved"
|
|
description: "More information on why systemd-resolved marks the installation as unsupported."

|
## The issue
|
|
|
|
systemd-resolved is used over D-Bus to resolve DNS queries made by Home Assistant, Supervisor,
|
|
and add-ons. Without it, DNS will not work correctly in your installation.
|
|
|
|
## The solution
|
|
|
|
If you see a message about an issue with D-Bus, [resolve that first](/more-info/unsupported/dbus#the-solution).
|
|
|
|
If the systemd-resolved service is not running or disabled, enable and start it.
|
|
|
|
If that does not help, reboot your operating system.
|
|
|
|
As a last resort, you need to reinstall the host running the Supervisor
|
|
with one of the supported operating systems, [see instructions here](/more-info/unsupported/os).
