[SOLVED] Network does not come up after boot

[f99]

Hi all,

My install went successful-ish (it hung on the reboot and I had to force power cycle it). However, the system has no networking on boot. I checked the systemd networking unit and it shows this error:



I'm not sure why this happens. If I run the following command, the networking starts working as expected.

/usr/share/ifupdown2/sbin/start-networking start

Any ideas on what I should do?

sudo systemctl is-enabled networking should return enabled. If not, sudo systemctl enable networking should get networking starting with boot.

As you can see in the screenshot it is already enabled and the error in the log is from when it attempted to start but could not. Does anyone have any idea what dependency might be failing?

Figured it out, the ifupdown2-pre.service was erroring. I checked what it was supposed to do and it was related to udev sync which seemed safe to disable. I removed this dependency from the `networking.service` unit and now it starts without any issues.
