I'm attaching DNS logs of a steam session using systemd-resolved, and of one using Google directly.
** Attachment added: "dns packet capture without resoled" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1653495/+attachment/4799003/+files/dns-google.pcap -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1653495 Title: systemd-resolved breaks Steam Status in systemd package in Ubuntu: New Bug description: When systemd-resolved is active and /etc/resolv.conf points to 127.0.0.53, steam fails to resolve domain names, and refuses to update or install games. Often, it doesn't even start, because it wants to update itself, but cannot reach its content servers. Manually (dig/host/nslookup/etc), resolving works fine, and also Chrome etc do'nt show any problems. It seems Steam uses some uncommon type of DNS records or so? If I change the nameserver in /etc/resolv.conf to 8.8.8.8, of to my local resolver, everything works fine again.
