I upgraded my 22.04 LTS desktop to 24.04.1 LTS on a Dell Inspiron 15 3520, and it failed at the end. I booted from a USB drive and was able to finish the installation, but I'm getting Network Unavailable (can't access my Wi-Fi and have no ethernet board).
I tried to reinstall systemd-resolved locally (downloaded from another PC), but it didn't work.
Tried this, also didn't work.
I've read here that NetworkManager and systemd-enable are incompatible, and tried keeping just one of them enabled (did it for both), but it didn't work.
systemctl restart [service] for both NetworkManager and systemd-resolved returns:
Job for [service] failed because a fatal signal was delivered causing the control process to dump core.
See "systemctl status [service]" and "journalctl -xeu [service]" for details.
