OK! I will try to fix the update code.
Anyway, we have a new green build (buster):
https://os.zynthian.org/2020-02-28-zynthianos-buster-lite-1.0.0.zip
I’ve not tested yet, but it should include all the new changes

Excellent. Ithe os pageis a little confusing as to precisely what is andisnt a clean build. We’ll it is to me anyway
OK, here’s what I’ve done.
I flashed a Zynthian image backup from 19 January 2020 to my SD card. I powered on my Zynthian and connected to the WiFi. I selected Update Software in the Zynthian UI. After the obligatory scrolling text, the screen turned all white. The Zynthian UI was gone.
I rebooted the Zynthian over SSH, but the screen was still white. I tried running update_zynthian.sh, and I got the error everybody’s been talking about:
Traceback (most recent call last):
File "./zynthian_lv2.py", line 28, in <module>
import lilv
ModuleNotFoundError: No module named 'lilv'
(At this point, the screen was still white.)
Then I ran the script that @mheidt mentioned…
…and ran update_zynthian.sh again. This time, the screen showed the Zynthian UI, but I still got the error message:
Traceback (most recent call last):
File "./zynthian_lv2.py", line 28, in <module>
import lilv
ModuleNotFoundError: No module named 'lilv'
Hope this helps. I’ll look into it more tomorrow.
That’s weird. My build from Januar-15 worked. Only an early build had issues.
But let the install_lv2_lilv be the last action.
The update seems to delete it again.

Hello,
I just updated. Problem while trying to add an affect layer:
I can select any LV2 plugin then I see the usual logo animation but the screen to select a channel or a preset never appear. I can just push “back” button to return to main menu.
The effect layer doesn’t seem to be created (audio can’t be routed to it).
Any clue ?
Is the webconf running? If not, read the solution in this thread. It might be related
Yes webconf is running. And I updated from webconf. I saved the logs if it can be usefull later…
I also tryed
Not fixed yet.
And I am downloading latest build (5 hours left with my poor connection to internet)
But I will try it only if other solutions don’t work.
Hi @zynthianers!
Those having problems with the last update … could you try updating again?

For me it didnt solve the problem. But I also did some other things which might have broken it again. For example I switched from master to faster repository for some time and than switched back. I also did an sudo apt update. Now I am flashing the old original rc3 image again.
I just updated.
Everything is way faster.
As of now everything works.
