When attempting to display any notification with notify-send I get:

GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: 
The name org.freedesktop.Notifications was not provided by any .service files

I also noticed that $HOME/.dbus/ disappeared. It was working before although I use notify-send only via scripts that are run by cron. I have DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus in my crontab. notify-send is to notify me only in case of an emergency - and there was none as far as I know. I update my Ubuntu Desktop 22.04 LTS with apt every twelve hours, could such update be responsible for the issue? I have libnotify-bin installed. I've found people describing a similar issue but am hesitant to apply their fix as I do not know much about dbus and freedesktop.

How should I resolve this issue?

This worked for me on Ubuntu 22.04:

sudo nano /usr/share/dbus-1/services/org.freedesktop.Notifications.service

[D-BUS Service]
Name=org.freedesktop.Notifications
Exec=/usr/lib/notification-daemon/notification-daemon

Adding this mostly for the search engines, cause i also landed here.

This answer below still works on Ubuntu 24. No need for additionals. Your box has everything you need already installed. Dbus: look in /run/user/$uid. And before people go into the rabbit hole of apt install -y notification-daemon (old, not required) and apt install dbus-x11 (dito), please see the linked answer.

Beside Debian based distro like Ubuntu also in RPM based like fedora same problem is persisted.

As wall command no longer works anymore we can use notify-send command.

Install the requirement to send message to another program

apt install notification-daemon

Use with:

notify-send dorood
