[SOLVED]dbus and systemd: "systemctl --user" gets "Connection refused"

Hi,
I want to enable some systemd user service. Here is what I get

$ LANG=C systemctl --user
Failed to get D-Bus connection: Connection refused
$ echo $DBUS_SESSION_BUS_ADDRESS 
unix:abstract=/tmp/dbus-RboLZS2wF3,guid=feb8bd85248906d12a826acd54e3c4ad

I don't believe I've ever touched dbus, so I'm a bit lost. There's the following line in my ~/.xinitrc:

exec dbus-launch xmonad

Seems like I'm not the only one with trouble on that topic, but I could not solve my problem.

Additional resources:
1. relevant pstree information

systemd-+-acpid
        |-at-spi-bus-laun-+-dbus-daemon
        |                 |-{dconf worker}

        |-systemd-logind
        |-systemd-udevd

2.

$ pgrep -af systemd
1 /usr/lib/systemd/systemd --system --deserialize 16
149 /usr/lib/systemd/systemd-journald
171 /usr/lib/systemd/systemd-udevd
257 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
263 /usr/lib/systemd/systemd-logind
316 /usr/lib/systemd/systemd --user

3.

$ pgrep -af dbus
257 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
385 dbus-launch --sh-syntax --exit-with-session
386 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
459 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
470 /usr/bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3

4. Playing with processus #1
- Killing it doesn't change anything

$ /usr/lib/systemd/systemd --user
Failed to create root cgroup hierarchy: Permission denied
Failed to allocate manager object: Permission denied
$ sudo /usr/lib/systemd/systemd --user
Trying to run as user instance, but $XDG_RUNTIME_DIR is not set.
$ echo $XDG_RUNTIME_DIR 
/run/user/1000
$ sudo -i
# XDG_RUNTIME_DIR=/run/user/1000 /usr/lib/systemd/systemd
Startup finished in 41ms.       // keeps running

But I still cannot do "systemctl --user"....

Re: [SOLVED]dbus and systemd: "systemctl --user" gets "Connection refused"

Heyyy I'm dumb!

 $ alias systemctl
alias systemctl='sudo systemctl'
$ LANG=C /usr/bin/systemctl --user
Failed to list units: Process org.freedesktop.systemd1 exited with status 1

New error = progress! yay!

Re: [SOLVED]dbus and systemd: "systemctl --user" gets "Connection refused"

And after a reboot everything's fine... I had an update pending. Solved!
