Failed to activate service 'org.freedesktop.systemd1': timed out

Solution 1:

As it clear from looking through the output of the busctl call published above by you, your org.freedesktop.systemd1 daemon (init.scope unit) isn't active actually:

org.freedesktop.systemd1             - -               -                (activatable) -                         -

However it might be activated like this:

$ systemctl daemon-reexec

Or this:

$ sudo kill 1

Which should ask systemd, in a little bit more insistent manner - by sending a SIGTERM signal to systemd, to do essentially the same - run daemon-reexec. I encountred a look-alike problem after depleting all the free RAM while not having a swap file on the system. And reexecing the systemd daemon totally solved it for me without the need to reboot the machine (Though before it you would need to kill some user processes to free some RAM if the problem was caused in the same way as in my case). As it stated in the systemd's man pages, daemon-reexec is save to use:

   daemon-reexec
       Reexecute the systemd manager. This will serialize the manager
       state, reexecute the process and deserialize the state again. This
       command is of little use except for debugging and package upgrades.
       Sometimes, it might be helpful as a heavy-weight daemon-reload.
       While the daemon is being reexecuted, all sockets systemd listening
       on behalf of user configuration will stay accessible.
