How to troubleshoot DNS with systemd-resolved?

Very helpful for troubleshooting is also:

journalctl -u systemd-resolved -f

There you can see what systemd-resolved is really doing. In my case it was not contacting the DNS servers that were reported via systemd-resolve --status at all. If it's doing weird things like that, then somtimes a restart via sudo systemctl restart systemd-resolved is a good idea.


In order to get more information from resolved you need to put


into the override.conf of systemd-resolved via

sudo systemctl edit systemd-resolved

Restart to take effect:

sudo systemctl restart systemd-resolved

Use resolvectl status (systemd-resolve --status when using systemd version earlier than 239) to show your global and per-link DNS settings.
