Solved: Help: DNS Broken in 29.1

🚀 Executive Summary TL;DR: After a system update, DNS resolution can fail due to systemd-resolved losing its upstream DNS configuration, even if direct IP pings work. The recommended solution involves configuring /etc/systemd/resolved.conf to specify DNS servers and domains, ensuring systemd-resolved correctly manages /etc/resolv.conf . 🎯 Key Takeaways In modern Linux, /etc/resolv.conf is often a symlink managed by systemd-resolved , which acts as a local DNS stub resolver on 127.0.0.53 . System updates, network manager changes, or cloud-init scripts can overwrite systemd-resolved ’s internal configuration, leading to name resolution failures. The most robust solution is to configure systemd-resolved directly via /etc/systemd/resolved.conf by setting DNS , FallbackDNS , and Domains directives, then restarting the service.
