One of your session-configuration-directories cannot be read by dbus-broker. I assume it has the wrong permissions. The standardized D-Bus configuration directories are: - $XDG_RUNTIME_DIR/dbus-1/services/ - $XDG_DATA_HOME/dbus-1/services/ - $HOME/.local/share/dbus-1/services/ - $XDG_DATA_DIRS (append ./dbus-1/services to each) - /usr/local/share/dbus-1/services - /usr/share/dbus-1/services If a variable is not set, the directories are skipped. Each of these directories, if it exists, must be readable+executable by dbus-broker. The permission of /usr/share/dbus-1/services directory are as follows drwxr-xr-x. 2 root root 4.0K Apr 9 21:44 services/ Should i chmod it to dbus:dbus?

No. This is fine. What about the other directories I listed? # find / -name 'dbus-1' -type d | xargs -I '%' bash -c 'test -e %/services && echo % && ls -lh %' /usr/share/dbus-1 total 44K drwxr-xr-x. 2 root root 4.0K Apr 30 23:22 accessibility-services drwxr-xr-x. 2 root root 12K Apr 9 21:44 interfaces drwxr-xr-x. 2 root root 4.0K Apr 9 21:44 services -rw-r--r--. 1 root root 3.5K Apr 9 21:43 session.conf drwxr-xr-x. 2 root root 4.0K Apr 9 21:44 session.d -rw-r--r--. 1 root root 5.6K Apr 9 21:43 system.conf drwxr-xr-x. 2 root root 4.0K Apr 9 21:44 system.d drwxr-xr-x. 2 root root 4.0K Apr 9 21:44 system-services /usr/local/share/dbus-1 total 8.0K drwx------. 2 root root 4.0K Sep 26 2018 interfaces drwx------. 2 root root 4.0K Sep 26 2018 services I tried chmod 755 on both interfaces and services directories (even though they are empty) still doesn't work.

All the directories I listed must be accessible as a normal user. The session-bus or user-bus runs under your user-ID. Only the **system-bus** runs as `dbus:dbus`. So this means `ls $DIR` must work as your normal user. In your case, both the `interfaces` and `services` directories need `755`. Furthermore, I suspect their parent directories have wrong permissions as well. So `/usr/local`, `/usr/local/share`, `/usr/local/share/dbus-1` all need `755` as well. Note that you can safely remove these directories in case they are empty. I now pushed a fix to dbus-broker upstream to ignore EACCES in `opendir()` to align it with the behavior of dbus-daemon. However, you should still fix these permissions, since it means anything installed into these directories will be ignored by dbus-daemon and dbus-broker, and thus it will not work. Thanks David Looks like its working now, thanks. dbus-broker-21-2.fc30 has been submitted as an update to Fedora 30. https://bodhi.fedoraproject.org/updates/FEDORA-2019-4c057073ca dbus-broker-21-2.fc30 has been pushed to the Fedora 30 testing repository.
