[Bug 2040051] Re: systemd-networkd-wait-online terminates with "Could not create manager: Invalid argument"

[Matthias Nagel]

Maybe it is nothing, but please not that the file path has changed with
23.10. It is not `/usr/lib/...` anymore, but only `/lib/...`.

The error messages comes from
https://github.com/systemd/systemd/blob/2c87b71b00523ef2aecdd2b68e61008b7d2e5ecc/src/network/wait-
online/wait-online.c#L217 (and it is similar, though a different
executable for bug #2040055).

Moreover, `systemctl status` reports

● h2917298.stratoserver.net
    State: degraded
    Units: 220 loaded (incl. loaded aliases)
     Jobs: 0 queued
   Failed: 3 units
    Since: Sat 2023-10-21 15:43:27 CEST; 2 days ago
  systemd: 253.5-1ubuntu6
  Tainted: unmerged-usr:cgroupsv1

Note that the line `Tainted: unmerged-usr` is new since 23.10. (The
complaint about cgroupsv1 is really old and around since 21.04.) I know
from another distro, that systemd has recently moved out everything from
`/usr`. So maybe it has something to do with that, but it is really a
shot in the dark.

Title:
  systemd-networkd-wait-online terminates with "Could not create
  manager: Invalid argument"

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  # lsb_release -rd
  No LSB modules are available.
  Description:    Ubuntu 23.10
  Release:        23.10

  # aptitude show systemd
  Package: systemd                         
  Version: 253.5-1ubuntu6
  State: installed

  systemd-networkd-wait-online terminates with "Could not create
  manager: Invalid argument".

  This lets the corresponding service (systemd-networkd-wait-
  online.service) fail as well. The error also appears when one directly
  invokes /lib/systemd/systemd-networkd-wait-online from a shell.
