Problem on webconfig ( cannot be started)


Hi folks,

I have tried to build a new zynthian with latest image and it works great.

However, webconfig could not be started after updating the software with /zynthian/zynthian-sys/scripts/, and this is the error message when I tried to run the webconfig manually

root@zynthian:/zynthian/zynthian-webconf# ./
Traceback (most recent call last):
File “./”, line 48, in
from lib.midi_config_handler import MidiConfigHandler
File “/zynthian/zynthian-webconf/lib/”, line 38, in
from zyngine.zynthian_midi_filter import MidiFilterScript
File “/zynthian/zynthian-ui/zyngine/”, line 28, in
from zyngine.zynthian_engine_puredata import *
File “/zynthian/zynthian-ui/zyngine/”, line 30, in
import oyaml as yaml
ImportError: No module named ‘oyaml’

Any clue?



Hi Francis!

The update has failed, i don’t know why. The oyaml package should be installed after updating but it’s not, so …

1.) You can try to install it by hand with “pip3 install oyaml”

2.) Better, re-burn the SD and update again

Kind Regards!

Thanks for the reply and I try to solve it by reinstalling the package.
