Comment 15 for bug 2063333

I had the same problem reported in this bug, on my notebook.

After executing the command:
$ sudo systemd-sysusers

The user has been created
gnome-remote-desktop:x:989:989:GNOME Remote Desktop:/var/lib/gnome-remote-desktop:/usr/sbin/nologin

I restarted the notebook and the service started working:
● gnome-remote-desktop.service - GNOME Remote Desktop
     Loaded: loaded (/usr/lib/systemd/system/gnome-remote-desktop.service; enabled; preset: enabled)
     Active: active (running) since Fri 2024-05-03 08:02:27 -03; 7min ago
   Main PID: 1082 (gnome-remote-de)
      Tasks: 4 (limit: 47715)
     Memory: 14.2M (peak: 18.2M)
        CPU: 1.286s
     CGroup: /system.slice/gnome-remote-desktop.service
             └─1082 /usr/libexec/gnome-remote-desktop-daemon --system

Strangely, on another notebook I have, I performed the update and the user was created automatically. I believe it is because the notebook that automatically installed has only 1 user, while the one that returned the error described in the bug has 2 users.
