Infinitely shows 'Collecting information'

Could you paste this into a file, and run python3 /path/to/file.py :

#!/bin/python3
from UbuntuDrivers import detect
print(detect.system_device_drivers())

And comment back on whether the script ever completes?

Yes, completes in about 3 seconds.

Output:
{}

I need some more info :)
Please go through the following steps :

1) Install & start bustle
2) Start recording a new log
3) run : qdbus org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.getDriverDict true
4) Stop logging
5) Attach logs here.

Thanks!

Hmm... qdbus prints error and bustle records no messages

$ qdbus org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.getDriverDict true
Cannot find 'org.kubuntu.DriverManager.getDriverDict' in object /DriverManager at org.kubuntu.DriverManager

Can you check if you have both /usr/lib/kde4/libexec/DriverManager_DBus and /usr/share/dbus-1/services/org.kubuntu.DriverManager.service ?

> Can you check if you have both /usr/lib/kde4/libexec/DriverManager_DBus and /usr/share/dbus-1/services/org.kubuntu.DriverManager.service ?

/usr/lib/kde4/libexec/DriverManager_DBus
exists, is a Python script, is executable

/usr/share/dbus-1/services/org.kubuntu.DriverManager.service
exists, contains

[D-BUS Service]
Name=org.kubuntu.DriverManager
Exec=/usr/lib/kde4/libexec/DriverManager_DBus

And can you check if running : qdbus org.kubuntu.DriverManager /DriverManager : works?

Seems like it does not.

$ qdbus org.kubuntu.DriverManager /DriverManager
Error: org.freedesktop.DBus.Error.Spawn.ChildExited
Process /usr/lib/kde4/libexec/DriverManager_DBus exited with status 1

Aha, can you run : python3 /usr/lib/kde4/libexec/DriverManager_DBus ? If it does, please try the getDriverDict dbus query please.

$ python3 /usr/lib/kde4/libexec/DriverManager_DBus
Traceback (most recent call last):
  File "/usr/lib/kde4/libexec/DriverManager_DBus", line 8, in <module>
    import dbus.mainloop.qt
ImportError: No module named 'dbus.mainloop.qt'

Missing dependency. After installing python3-dbus.mainloop.qt everything works.

Thanks!
Fixed in git

Fix should be released with 0ubuntu3

Fix doesn't seem to be complete atm.

Same symptoms, I runned all suggested tests here are the results:

Hi
Would it be possible for you to run this :

qdbus --literal org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.devices()

Since the method from the python script has changed.

Thanks!

$ qdbus --literal org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.devices()
bash: syntax error near unexpected token `('

$ qdbus --literal org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.devices

As for me, this just hangs.

$ qdbus --literal org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.devices
Error: org.freedesktop.DBus.Error.NoReply
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Hi
Please file a new bug with full details on steps you took to reproduce the problem , what you expected the output to be and what really happened.

Please also run kdebugdialog, enable debug output for everything and run the kcm via a console using the following command : kcmshell4 kcm_driver_manager

Oh and ofcourse, please attach the debugging output from the console to the bug report ^^ :)

@Sergey Could you run the script manually as mentioned before and then run the qdbus command?

@asavah Figured out your issue this morning, it's fixed and will land in 14.04ubuntu5 , cheers :)

@rohangarg
TYVM, sorry for not being to able to submit full report with kdebug,
I'm out of office atm, and the machine with fresh (k)ubuntu is there.

@asavah Whether has been resolved

@kmin
Can't tell, sorry.
I switched to mate de more than a year ago.

This is now broken again on Kubuntu 19.10

I also have this issue in Kubuntu 19.10.

Appears to be caused by:

```
qdbus org.kubuntu.DriverManager /DriverManager org.kubuntu.DriverManager.getDriverDict true
Cannot find 'org.kubuntu.DriverManager.getDriverDict' in object /DriverManager at org.kubuntu.DriverManager
```

Broken still in Kubuntu 20.04. Six years and counting.
