Hi,
I have a Zynthian box with a Rpi3. When I long press the shutdown button, I say “yes”. Then it is stuck on the Zynthian logo. I need to unplug the power and I don’t like that.
Where can I find logs to investigate?
The webcongf gui log will possibly give you information…
else you log on to the zynthian and investigate with the system d journal
journalctl -fu zynthian . .
When I look journalctl -f via ssh I got this:
Feb 16 09:39:11 zynthian startx[424]: zynseq exit
Connection to 192.168.1.124 closed by remote host.
Connection to 192.168.1.124 closed.
I can’t find the logs from the previous session.
When I do a shutdown -h now in ssh it’s shuting down properly.

I am currently updating it.
Still the same problem after update via web-ui

What is the command/script preformed when clicking on “YES” ?
Zynthian UI is run from a BASH script which monitors its exit status. If the exit status is 0 then the BASH scripts runs the poweroff command. If you are able to run poweroff successfully from the command line it suggests that zynthian is either not exiting or is returning a different exit value.
poweroff is working from comand line.
Try this:
systemctl stop zynthian
cd /zynthian/zynthian-ui
X :0 & DISPLAY=:0 ./zynthian_gui.py ; echo "EXIT CODE: $?" ; killall Xorg
Within Zynthian UI try to shutdown then see what is printed at the command line.
After executing your commands the ui doesn’t restart:
ERROR: PatternManager failed to open file for load /zynthian/zynthian-my-data/sequences/patterns.zynseq
In the meantime I enabled rsyslog. Maybe i will have more informations.
That error may be ignored and is removed from the development branch (soon to be merged).
here is what the log say:

It seems to stop properly except these two lines maybe:

zynthian killall[1218]: zynthian_gui.py: no process found
Apparently the system is mostly stopped anyway. I think I can unplug the power without damaging the sdcard.
It will be good to resolve this though…
Will you describe the steps you took to get your device to this state? What image did you flash and how? What updates did you apply, etc.
Hi @Djeremaille !
I see you are running an older SD image and updates can cause problems with it. Also, i remember to have the same problem you have with older SD images. I strongly encourage you to try the latest stable SD image:
https://os.zynthian.org/2020-09-05-zynthianos-buster-lite-armhf-1.0.0-RC3.zip
Regards!
Thanks @jofemodo . I am downloading the latest stable image at the moment. Is this the same as the 1.0.0-RC3?
Apparently not. I will download the RC3
Edit: Yes It is the same md5
Fresh flash. No updates. Just changed from v4 to v1 in the web-ui then rebooted.
Screen and encoders are working.
Long press button 4. Press Yes. Raspberry hang on the zynthian screen and don’t power off.
Maybe I have a wiring problem. I have to check that.
I give up for the moment…
Do you let go of the long press?
Yes I do
