No session for pid xxxx

[Ibrahim3773]

"no session for pid" displays again and again after running the raspberry_pi_initial_setup.sh

Could you give me more information?
For example which OS you're using.

After some googling I found these few links:

• https://www.raspberrypi.org/forums/viewtopic.php?t=172459
• https://www.raspberrypi.org/forums/viewtopic.php?p=846462
  It seems that it is related to VNC.

It could be that the update & upgrade step in raspberry_pi_initial_setup.sh could have update something that is causing that error to appear.

First of all, thank you so much for the quick response.

OS: 2018-05-27 Rasbian Stretch
Raspberry Pi 3B

The error is occurring when I run the command "sudo sevice dbus restart"
I have also tried to run this command before running the raspberry_pi_initial_setup.sh but i failed

[AnesBenmerzoug]

No worries, I noticed it on time so I had to reply.

Do you by any chance connect to your raspberry pi using vnc?
Does this error appear only after restarting dbus? Does it persist or does it go away?
Does it appear again if you restart the pi?

[Ibrahim3773]

No, we are not connecting it using vnc.
Yes, This error appears whenever a restart the debus.
The error persists and periodically appears after every 1-2 minutes.
No, when we reboot the pi, the error doesn't appear.

[AnesBenmerzoug]

Hmm, that's interesting.

Another question, what happens if right after restarting the raspberry pi you try to restart the dbus service without running the raspberry_pi_initial_setup.sh script?

In that script a configuration file is copied from the repository into the /etc/dbus-1/system.d directory.
Could you try deleting it and restarting the dbus service again?

[Ibrahim3773]

Same issue persists when I try to restart the dbus service after rebooting the raspberry pi.

I tried to restart the dbus service after deleting the "org.upwork.hidbluetooth.conf" file from "/etc/dbus-1/system.d" but the same error occurred again.

[AnesBenmerzoug]

Then I really don't know what could be causing this issue.

All I can suggest for now is to try to install a newer version of Raspian OS as
it seems that there a version that was released in November 2018 (https://www.raspberrypi.org/downloads/raspbian/)

I hope that you can solve this issue.

[Ibrahim3773]

I have tried it on the new version but still the error persists. Thank you so much for your time. Can you please tell me the version of Raspbian you used to run this code successfully?

[AnesBenmerzoug]

This project has currently some issues and I am trying to improve it.
I was busy these past few months so I didn't touch it in a while.
Last time I ran it I used the latest version, which is the one I linked above.

Hey, i was sucessful in run scripts in command line mode(non graphical mode). but after that the program didnt work..

[AnesBenmerzoug]

@speicherspule Could you tell me exactly what you did and what happened? I might be able to help you if I have more information

[speicherspule]

i'm using last RPi 3b+ with last raspbian and after running all the scripts, i connect bluetooth with my pc or phone and get this error.

[AnesBenmerzoug]

@speicherspule sorry for the late reply. I was busy the last few days.
This error is one I got quite a lot, but unfortunately I don't remember how I solved it.
It happened because you pressed a button from the interface without the connection being established so it timed out.
This project in it's current state is not quite functional and I would love to one day improve it.

Hi, I have the same problem on my raspberry pi 4b. It seems that this is a problem on newly devices.

Hi there, just wanted to chime in with my own problem to this.
I have a brand new raspberry pi 4 that I've set up. As I was planning on locking up the pi in a closet, I wanted VNC to work, but would not auto start so would need to SSH into it to send "vncserver :1" to then be able to VNC in.
To fix this I went into "crontab -e" and added "@reboot vncserver :1 -geometry 1600x900"

After setting this up, on launch I would get the error "No session for pid xxxx".
Issue was solved when I typed: mv /usr/bin/lxpolkit /usr/bin/lxpolkit.bak

EDIT: Solution was from here: meefik/linuxdeploy#978 (comment)
