I was trying to diagnose why i had a load of ordering cycle errors in my startup. GPT suggested i try disabling NetworkManager-wait-online.service but now, even though i enabled it, i can not get it to work at boot any more.

I have disabled all my samba automounts which did seem to be causing all the cycle errors but the NetworkManager-wait-online.service still failed to start at boot

No journalctl entries at all? It just is not even trying to start.

I can start the service, its status looks like after that

But as soon as i reboot, it fails to load/start at all and leaves no entries in the logs? (it is enabled).

If you know how to disable a service, how do you not know how to enable it? Of course, just starting the service won’t make it run again at boot.

3

no but enabling it will and thats what iv have. Its enabled.

Something is wrong here. Why does that file exist? What did you do? This is what it should look like:

Hi,

Now thats a very good question. I have no clue. all i did was disable the service reboot and see it was not helping with my original problems and so i just enabled it again.

I have just searched my history for all commands issued today with the term “NetworkManager-wait-online”

09/02/24 21:02  history --merge; history search --show-time="%D %H:%M  " NetworkManager-wait-online
09/02/24 20:24  sudo systemctl status NetworkManager-wait-online.service

09/02/24 20:23  sudo journalctl -u NetworkManager-wait-online.service -b
09/02/24 20:21  sudo systemctl cat NetworkManager-wait-online.service

09/02/24 18:32  sudo systemctl disable NetworkManager-wait-online.service

I honestly don’t think i moved anything :scratches head:

What should i do, move it? re-install networkmanager? hmm

This did it.
Created /etc/systemd/system/NetworkManager-wait-online.service I mean.

Just delete your custom file.

sudo rm /etc/systemd/system/NetworkManager-wait-online.service

O, you better explain exactly how as iv only just figure that i can use edit --full and if its got something that important that i should know then i’d love to know.

I do have all the files in /usr/lib/systemd/system but i also have these in /etc/systemd/system

Most are mine, some need cleaning up. Heres a ls of them just in case its of help to you.

What do you mean?

You run that command - it creates the file in /etc/* for you to edit.
Which is intended to augment the existing /usr/lib/systemd/system/NetworkManager-wait-online.service which you should not edit by hand.

10

O, i thought that edit was to create a drop-in, and --full was to edit the actual unit file rather than having to get it path and then sudo micro path

However, you know what they say about assumption ^^

Thank you very much :slight_smile:

What else do i need to do?

I deleted the other one, i have disabled then re enabled the proper one, stopped and started it but it still says this for the status after boot

The issue this topic is about has been solved and is now closed.

Create a new topic about the actual problem you were having to begin with instead of an issue you had with the imagined (or hallucinated by useless AI) solution. That’s the definition of an XY Problem. :wink:
