[notice] dbus does not allow qomui.service by default on openSUSE Leap 15.0

[ChaosNicro]

Using the packaged Version of 0.8.0 the GUI failed to start the service.
Running sudo qomui-service manually, I got:

Traceback (most recent call last): File "/usr/bin/qomui-service", line 11, in <module> load_entry_point('qomui==0.8.0', 'console_scripts', 'qomui-service')() File "/usr/lib/python3.6/site-packages/qomui/qomui_service.py", line 645, in main service = QomuiDbus() File "/usr/lib/python3.6/site-packages/qomui/qomui_service.py", line 58, in __init__ self.bus_name = dbus.service.BusName(BUS_NAME, bus=self.sys_bus) File "/usr/lib/python3.6/site-packages/dbus/service.py", line 131, in __new__ retval = bus.request_name(name, name_flags) File "/usr/lib/python3.6/site-packages/dbus/bus.py", line 303, in request_name 'su', (name, flags)) File "/usr/lib/python3.6/site-packages/dbus/connection.py", line 651, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Connection ":1.143" is not allowed to own the service "org.qomui.service" due to security policies in the configuration file

I don't know much about the system-dbus but the policy seems to block "unregistered" services by default.
My solution was to create a minimal policy for the service:
/etc/dbus-1/system.d/org.qomui.conf

<policy>
    <allow own="org.qomui.service"/>
</policy>

I'm not actually certain that it is the default setting but I did not change any settings in the dbus-service. Should this be a problem for other users, you may want to place a similar configuration and reload the dbus-service during installation. If this is actually just me, please feel free to close this.
After this change, everything started fine and is working as expected.

Setup used:
Opensuse Leap 15.0
qomui 0.8.0 from corrad1nho's Opensuse repository

I had this issue in the past; sometimes a restart of dbus (or a system reboot) was necessary in order for the policy file to be recognized properly on some distributions. A custom policy file shouldn't be needed as I already included one.

I did a fresh install of OpenSuse Leap 15 and couldn't reproduce this issue. But I just realized that you are starting qomui-service manually. What happens if you use systemd?
systemctl start qomui

For version: qomui-0.8.1

No issues with versions -0.7.4 -0.7.3 (works great- it’s a wonderful app- thank you for creating it)

I initially started with 0.7.4 (currently using 0.7.3 since I can’t find .deb installer for 0.7.4)

System info: Linux Mint 18.3 (Ubuntu 16.04)

I am a relative novice with Linux, so the info I am including may either be too much or too little- but I hope it will help.

I have attempted to upgrade to version 0.8.1 multiple times on two different Linux computers (one a laptop, the other a desktop). Same issues for both. Each time, I also ensured that the listed dependencies/ required packages were also installed.

Methods tried:

1. adding the repository and upgrading through the update manager

2. through terminal (using commands you have listed)

3. downloading .deb package and using gdeb package installer

4. (after adding the repository) with the button on the qomui gui (this did not work at all)

5. reinstall via the synaptic package manager

Most recent attempt (so that I could share more detailed info with you):

@poisonowl: Please remove and then reinstall Qomui. For detail see #53.

Unfortunately, I have already tried uninstalling (and completely removing) and then reinstalling multiple times. It has been the same result each time (and has been a complete headache). So, I suppose I will stick with 0.7.3 until you release a newer version, and then give that one a shot.

Thank you for the link- somehow I had missed seeing that.

Deb packages were broken. It's fixed in v0.8.2. A re-install is required, though.
