Answer 1

You probably forgot to add something to the config, it is always possible to set dns individually locally.

sudo echo "nameserver 8.8.8.8" > /etc/resolvconf/resolv.conf.d/base
sudo echo "nameserver 8.8.4.4" > /etc/resolvconf/resolv.conf.d/head

Reboot
Look

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.4.4
nameserver 127.0.1.1

Like it. If the error repeats, then you can add vlob
Is there an option to put dnsmasq

sudo echo "server=8.8.8.8" >> /etc/dnsmasq.conf
sudo echo "server=8.8.4.4" >> /etc/dnsmasq.conf

By analogy, reboot and use.
