What I tried
sudo service NetworkManager status
NetworkManager is active running.
sudo service systemd-resolved start
Got error:
Failed to restart systemd-resolved.service: Unit systemd-resolved.service not found
My /etc/resolv.conf doesn’t exits。
sudo ln /usr/bin/resolvectl /usr/bin/systemd-resolv
Not working because /usr/bin/resolvectl not exists
Then I reinstalled systemd
sudo apt reinstall systemd
Unfortunately everything is still the same as above.
