I'm running Ubuntu Server 24.04.1 LTS and having issues doing things the "correct" ubuntu way.

First, I'm trying to get systemd-resolved to work:

  • I specifically want to use systemd-resolved and to keep caching. I also want to continue to run in stub mode.
  • If at all possible, I want to avoid un-symlinking or modifying existing files. I would rather add drop-in configs where possible.
  • The nameservers I specified via netplan appear in /run/systemd/resolve/resolv.conf, but /run/systemd/resolve/stub-resolv.conf is what's symlinked at /etc/resolv.conf.
  • resolvectl query google.com works as expected and caches responses.
  • host google.com does not work and returns communications error to 127.0.0.53#53: timed out.
  • systemctl status systemd-resolved shows the service running with a status of "processing requests".
  • lsof -i :53 shows systemd-resolve at 127.0.0.53 and 127.0.0.54 tcp + udp, but only the TCP entries have "(LISTEN)" next to them.

Second, I'm trying to disable ipv6 altogether:

  • I have set several values in /etc/sysctl.d/local.conf but this doesn't seem to be impacting anything after a reboot.
  • networkctl status shows my network in a routable state but a partial online state.

Not sure what I'm doing wrong but I feel like this is the hardest I've ever had to fight a linux install.

/etc/netplan/99-ip.yaml

network:
  version: 2
  ethernets:
    eno1:
      dhcp4: false
      dhcp6: false
      addresses:
      - 192.168.1.137/24
      routes:
      - to: default
        via: 192.168.1.254
      nameservers:
        addresses: [9.9.9.11,149.112.112.11]

/etc/sysctl.d/local.conf

net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.all.forwarding=0
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
net.ipv6.conf.eno1.disable_ipv6=1
