Hello I have removed the default systemd-resolved local dns service following the link below,
https://askubuntu.com/questions/907246/how-to-disable-systemd-resolved-in-ubuntu And I have unbound installed and enabled as local DNS server. But every time I reboot the server, the configuration file /etc/resolv.conf changes to a default one. So every time I have to update its content to: nameserver 127.0.0.1 (points to unbound) How to stop the auto-changes to /etc/resolv.conf after rebooting? Thanks.
