Description Jon 2023-04-24 16:18:40 UTC 
When installing cups I see a few dbus errors:  
```
Apr 23 16:07:35 ipfireAPU dbus-daemon[1991]: [system] Unable to reload configuration: Failed to open "/usr/share/dbus-1/system.conf": No such file or directory
Apr 23 16:07:35 ipfireAPU dbus-daemon[1991]: Unable to reload configuration: Failed to open "/usr/share/dbus-1/system.conf": No such file or directory
```

And this error:
`Apr 23 16:07:36 ipfireAPU useradd[4920]: failed adding user 'messagebus', exit code: 9`

On my test box I see these error back to Dec 2022 (CU 172).
On my production box I see these error back to June 2022 (CU 168).


Here are more lines from the message log:

Comment 1 Jon 2023-04-24 16:32:22 UTC 
If I remove CUPS and then install CUPS I see the same errors (except for the user add error)

Also this is tested on:

Comment 2 Jon 2023-04-24 19:40:19 UTC 
it looks like the message "failed adding user 'messagebus', exit code: 9" is not a big issue (it could be ignored).

This can be easily fixed by updating the dbus (messagebus) `install.sh` file.

remove this:
`useradd messagebus`

and replace with this:
`id -u messagebus &>/dev/null || useradd -r -d /var/empty -s /bin/false messagebus`


I am not sure about the "Failed to open "/usr/share/dbus-1/system.conf": No such file or directory" error message since the files exists and looks OK.


```

> messagebus`

Yes, this is how it should be. Probably it is the same in other places where we create custom system users.

Would you like to propose a patch?
Comment 4 Adolf Belka 2023-04-25 10:02:31 UTC 
I don't see those messages on the Core-Update 175 Development Build: bug-12924/3274424a-dirty that I have running for my Cups build work.

I uninstalled all cups related programs and then installed cups and its dependencies and here is the log I got.

dbus installed without any messages from the post-installation scripts.

I will do the same test on a CU174 vm system and report back.
Comment 5 Adolf Belka 2023-04-25 10:40:27 UTC 
Just tested installing cups in a Core Update 174 system and no problems again. The same sort of log messages as in my last try, just some of the mirror names are different.

No error messages anywhere and definitely not related to dbus.

The permissions and ownership of /usr/share/dbus-1/system.conf on my systems are the same as you have shown.
Comment 6 Jon 2023-04-25 19:45:50 UTC 
I'll try building up something from scratch.

I can trace the same error back a few years.  The earliest I found the error is Feb 8 2019 on CU 127.

From the message logs, it looks like it happened when I removed cups and dbus (and dependency files).

Yes, I can do that!
Comment 8 Jon 2023-04-25 19:59:57 UTC 
I wonder (out loud) if messagebus needs to stop before uninstalling dbus?
Comment 9 Jon 2023-04-25 20:07:20 UTC 
never mind...  It looks like it stops.
Comment 10 Adolf Belka 2023-04-25 20:47:09 UTC 
(In reply to Jon from comment #9)
> never mind...  It looks like it stops.

Yes the uninstall.sh file has a stop_service command before removing all the files.
Comment 11 Jon 2023-04-26 03:07:20 UTC 
hmm it may not be working...

```
Comment 12 Adolf Belka 2023-04-26 07:43:04 UTC 
When you told pakfire to remove dbus, had you already removed cups, avahi and ghostscript. All of those packages depend on dbus and it acts as the communication bus between them. As long as one of those is still present then the dbus daemon will stay in place because it is being used.

At least that is my understanding of how it is likely to work.

so remove cups, ghostscript, avahi and dbus and check again after that.

You can also use theinitscript status command to see what it thinks the status is
/etc/init.d/messagebus status
Comment 13 Adolf Belka 2023-04-26 08:42:23 UTC 
You probably had removed the whole set of cups related packages.

I just did that and found the same as you. So yes it looks like the killproc command in the initscript is not working as expected.

Reading through the code for the killproc then if it finds that the pid is still in existence it should provide a failure message but that doesn't happen so it looks like the request does not end up in the right if loops of the killproc code.
It is a bit more complicated than I am able to follow.

I think that you should raise that as a separate bug. The dbus-daemon just seems to keep running unless a reboot is done and that is not correct, plus there is no error message that ends up in the log file.
Comment 14 Adolf Belka 2023-04-26 08:51:12 UTC 
I have figured out wht the problem is with the dbus daemon.

The messagebus initscript stop command is working fine. The problem is that the command in the paks uninstall.sh file is

stop_service ${NAME}

which takes the package name which is dbus but the initscript is called messagebus.

So the uninstall.sh file tries to run

/etc/init.d/dbus stop

which of course doesn't exist.

If you run /etc/init.d/messagebus stop

then the daemon is actually stopped.


Interestingly the install.sh script has

start_service messagebus

so it was done correctly for the install.sh script but not the uninstall.sh script.


I will raise a separate bug for that issue and raise a patch fix for it.

I think you should still be okay. Your patch is for install.sh while mine was for uninstall.sh.

The PAK_VER bump is to ensure that dbus will be shipped in the update so it only needs to be done once.

I would suggest doing a patch for install.sh and in the commit message say that the PAK_VER bump from my commit will also cover your patch. I think that should be okay.

Alternatively you can ask on the dev mailing list for how to deal with it.
Comment 18 Jon 2023-04-26 16:31:46 UTC 
I think I got it! 

I'll commit only the install.sh and ignore the dbus lfs file.
Comment 19 Adolf Belka 2023-04-26 16:35:09 UTC 
I believe that should be okay but I am not an expert :-)
Comment 21 Adolf Belka 2023-05-11 10:10:30 UTC 
The patch was marked as being for bug#13094 but it is actually for this bug 13090

Patch has been merged into next (will be CU175)

Comment 23 Jon 2023-05-22 17:56:35 UTC 
As far as the user messagebus goes, all works A-OK.  There are no more `ipfireAPU useradd[4920]: failed adding user 'messagebus', exit code: 9`` type messages.

Tested on:
APU4d4
IPFire 2.27 (x86_64) - Core-Update 175 Development Build: master/c6c78f8e

===

BUT - there is a new error (new for me!):

```
