After upgrade from 22.04 to 22.10, DNS does’t work anymore

Question

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.

No one works for my case.

"My /etc/resolve.conf doesn’t exits" I believe it is /etc/resolv.conf Let's take a look at: ls -al /etc/resolv.conf Welcome to Ask Ubuntu. — chili555, Apr 03 '23 at 13:49

It seems the systemd-resolved is not included in systemd in Ubuntu 20.10, after upgrading, I installed it manually,

sudo apt install systemd-resolved

Now everything works.
