Was chatting then I noticed my DNS had suddenly started working normally and YouTube resolved again.
I ran systemd-resolve --status Under "Link 2 (eth0)" it said "DNSSEC supported: no". I then restarted the computer, and now the DNS is broken again. It now says "DNSSEC supported: yes". Minutes later (perhaps coincidentally after I started Chromium for the second time?) my DNS magically works again, and systemd-resolve reports "DNSSEC supported: no". It seems DNS does not work when systemd-resolve reports "DNSSEC supported: yes". And it seems that DNSSEC changes to no and starts working for some reason, I am not sure if this is triggered by time or some user action such as starting a browser or something. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1647031 Title: systemd-resolved’s 127.0.0.53 server does not follow CNAME records Status in systemd: New Status in network-manager package in Ubuntu: Fix Released Status in systemd package in Ubuntu: Fix Released Bug description: $ systemd-resolve www.freedesktop.org www.freedesktop.org: 131.252.210.176 2610:10:20:722:a800:ff:feda:470f (annarchy.freedesktop.org) -- Information acquired via protocol DNS in 673.6ms. -- Data is authenticated: no $ ping www.freedesktop.org ping: www.freedesktop.org: Name or service not known $ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN # 127.0.0.53 is the systemd-resolved stub resolver. # run "systemd-resolve --status" to see details about the actual nameservers. nameserver 127.0.0.53 $ dig +no{cmd,comments,stats} www.freedesktop.org @127.0.0.53 ;www.freedesktop.org.
