Same issue occurred for me today on upgrade from 22.04 to 24.04. There
was some error during the initial upgrade, causing it to exit and it had
to be resumed. After the upgrade completed, `/etc/resolv.conf/` was
linked to `/run/systemd/resolve/stub-resolv.conf` however this file did
not exist. The package `systemd-resolved` was not installed or marked
for installation. To fix this, I installed the package resulting in
`/run/systemd/resolve/stub-resolv.conf` being generated, and after a
`sudo systemctl restart NetworkManager.service` DNS resolution worked
again.
Here is what I see in the relevant `main.log`:
```

```
So it seems like there was an unrelated error with the Firefox snap
installer. Perhaps the underlying problem is that `systemd-resolved` is
not properly reconfigured after upgrade errors?

Bug description:
I was an unpatient idiot, and I upgraded from 22.04 to 24.04. Near to
the end of the upgrade, I got an „Oh, no! Something has gone wrong and
the system cannot recover. Call the system administrator” message
after a red FAILED in the terminal. The system administrator is
myself, because my computer is a personal one. Hard reset, same error,
Ctrl+Alt+F3, sudo apt reinstall gdm3. Obviously. I needed to finish
the update with dpkg. While dpkg was upgrading, it printed an error
message for every WiFi connection:
„[Failed] Failed to migrate [I do not remember, something with
/etc/netplan]”
It took at least one and a half hour to find the solution on Ask
Ubuntu. The problem was: /etc/resolv.conf became a broken link, along
with systemd-resolve.service. I needed to remove both of them and
write a new resolv.conf to fix the error.
