    válasz cigam #43870 üzenetére

    Passz, én ebbe futottam bele még anno:

    Installing on Ubuntu
    Modern releases of Ubuntu (17.10+) include systemd-resolved which is configured by default to implement a caching DNS stub resolver. This will prevent pi-hole from listening on port 53. The stub resolver should be disabled with: sudo sed -r -i.orig 's/#?DNSStubListener=yes/DNSStubListener=no/g' /etc/systemd/resolved.conf
    This will not change the nameserver settings, which point to the stub resolver thus preventing DNS resolution. Change the /etc/resolv.conf symlink to point to /run/systemd/resolve/resolv.conf, which is automatically updated to follow the system's netplan: sudo sh -c 'rm /etc/resolv.conf && ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf' After making these changes, you should restart systemd-resolved using systemctl restart systemd-resolved
    Once pi-hole is installed, you'll want to configure your clients to use it (see here). If you used the symlink above, your docker host will either use whatever is served by DHCP, or whatever static setting you've configured. If you want to explicitly set your docker host's nameservers you can edit the netplan(s) found at /etc/netplan, then run sudo netplan apply. Example netplan:
    network:
        ethernets:
            ens160:
                dhcp4: true
                dhcp4-overrides:
                    use-dns: false
                nameservers:
                    addresses: [127.0.0.1]
        version: 2

    Note that it is also possible to disable systemd-resolved entirely. However, this can cause problems with name resolution in vpns (see bug report). It also disables the functionality of netplan since systemd-resolved is used as the default renderer (see man netplan). If you choose to disable the service, you will need to manually set the nameservers, for example by creating a new /etc/resolv.conf.
    Users of older Ubuntu releases (circa 17.04) will need to disable dnsmasq.
