Отключаем сервис systemd-resolved:
sudo systemctl disable systemd-resolved sudo systemctl stop systemd-resolved
Удаляем текущий /etc/resolv.conf это симлинк на /run/systemd/resolve/stub-resolv.conf
sudo rm /etc/resolv.conf
Создаем новый resolv.conf:
echo 'search mydomain.com' > /etc/resolv.conf echo 'nameserver 8.8.8.8' >> /etc/resolv.conf echo 'nameserver 1.1.1.1' >> /etc/resolv.conf echo 'nameserver 1.0.0.1' >> /etc/resolv.conf
