Could you be more specific about the problems you found?
Ups! Regarding 2020-05-14, the auto-delete system probably get ride of it. It deletes SD-images older than a week if they are not marked as RC.
But if we don’t find another working SD image, @wyleu can upload his copy to the server 
Regards,
of course I can be specific:
start with a new image: display error
Followed by about 5 minutes of black screen
Then very slowly fading in and out - zynthian - ERROR IP:
Zynthian directly connected to the router via LAN.
Display: ERROR IP: 169.254.100.40
webconf does not work over zynthian.local or over IP
continue via console:
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is

Add correct host key in /home/“user”/.ssh/known_hosts to get rid of this message.

You can use following command to remove the offending key:
ssh-keygen -R 192.168.178.24 -f /home/“user”/.ssh/known_hosts

Hi @spurkopf,
Please, could you send the webconf log?
Simply type:
journalctl -u zynthian-webconf -f
And try to access from the browser. Then copy/paste the output from the console. With this i could figure where the problem is and try to solve it for the next SD image builds.
Thanks!
No sorry, 2020_05_22 is already deleted. I have a copy of the 2020_05_17 UI log - I’m uploading it. But why mess with it, wouldn’t it be easier if you could say - this image worked for me - please test it?

testing 2020_05_16:
Zynthian doesn’t detect hardware, apart from the RBPi. SD images are pre-configured for a given hardware combination, depending on the image date. The latest ones are pre-configured for “Kit V3 - Pro”. What is your kit version @spurkopf?
According to your bill, I have:
Build from today(2020-05-23) is no candidate.
@jofemodo, webconf doesn’t start…mutagen

OK! I found the problem with mutagen and the SD build script:
# Install Mutagen (when available, use pip3 install)
$ZYNTHIAN_RECIPE_DIR/install_nutagen.sh
I just launched a new build for today (2020-05-24). It will finish in about 4 hours, about 21:00.

Hi José,
https://os.zynthian.org/2020-05-24-zynthianos-buster-lite-1.0.0.zip
is that the one we should test in priority ?
Nope, that’s from yesterday and still has the mutagen bug (tested this morning)
[In reply to “https://os.zynthian.org/2020-05-24-zynthianos-buster-lite-1.0.0.zip

]
Ok, thank you.
So far, I think running
$ZYNTHIAN_RECIPE_DIR/install_mutagen.sh
should solve the problem.
So except that “mutagen” bug, this version should be like the next one.
I will post a download link when a “good” candidate is ready. It should be in the next hours …
If of interest, I tried to install https://os.zynthian.org/2020-05-22-zynthianos-buster-lite-1.0.0.zip on official Kit V2. Initial boot showed error screen with IP adress. Webconf not working, but could ssh into zynthian. Then did update_zynthian.sh. webconf now working, zynthian boots regularly.
Then I tried to activate pianoteq stage, uploaded the pianoteq 7z binary. In the webconf screen, I tried to enter my license key, but got the error message (in webconf browser output): Pianoteq Action Failed: Command ‘/zynthian/zynthian-sw/pianoteq6/pianoteq --activate MY-LICENSE’ returned non-zero exit status 2. (I replaced actual license key for reporting). So I remembered the old way of activating: start pianoteq layer with a running ssh -X connection to zynthian. Then a window of pianoteq gui appears on the computer where activation info can be entered. So far, everything works fine.
But have mixer settings / audio been changed? Whenever I play some key, there is an accompanying noise that then fades out. Seems like the audio channel is opened (noisy) when active and then muted again. Tried to record the effect with zynthians audio recorder, and the effect is there when played back on the zynthian. But too low volume when played back on the computer so I cannot really demonstrate it. But it’s not the auto mute feature (which is turned off). It’s different. noise is of constant level, and it affects any engine.
I have hifiberry dac+adc.
–> edit: regarding the noise, I’ll try to investigate this: A weird noise is driving me mad [SOLVED]
My hardware hasn’t changed and the noise wasn’t there with previous official 2019-09-24-zynthianos-buster-lite-1.0.0-RC1.zip
ok, I’ve tested https://os.zynthian.org/2020-05-25-zynthianos-buster-lite-1.0.0.zip
Note also that I wasn’t able, using the mouse to get out from the ZY instrument screen
yes
Conclusion:
This is the image we have to test:
https://os.zynthian.org/2020-05-25-zynthianos-buster-lite-1.0.0.zip
I’ve fixed 2 errors in the setup script and it should work … i hope!
I will test it tomorrow, but if some of you want to try now, please, do it
Regards,
Curious … i fixed the error and it should be working …
At what time did you download the SD image from the server?
Regards
