Update problems/warning/errors [SOLVED]

C0d3man · February 18, 2024, 7:30am

I just started to update my “band” Zynthian (v4) from pre-latest to latest via webconf and recognized some problems/warnings/errors while updating from webconf:

Repository problem:

Ign:8 https://download.opensuse.org/repositories/home:/sfztools:/sfizz/Raspbian_10 InRelease
[...]
Err:10 https://download.opensuse.org/repositories/home:/sfztools:/sfizz/Raspbian_10 Release
404 Not Found [IP: 2a07:de40:b250:131:10:151:131:30 443]
[...]
Reading package lists...
E: The repository 'https://download.opensuse.org/repositories/home:/sfztools:/sfizz/Raspbian_10 Release' no longer has a Release file.

It seems that the path /repositories/home does not exist anymore. I also havn’t found any path with sfztools or sfizz.

webconf is not avaialble anymore after update (and reboot):

I logged in to see what’s going on. I tried to start webconf by hand (after setting all the environment from zynthian-webconf.service):

root@zynthian:/zynthian/zynthian-webconf# /zynthian/zynthian-webconf/zynthian_webconf.sh
INFO:zynthian_gui_config.<module>: ZYNTHIAN-UI CONFIG ...

  File "./zynthian_webconf.py", line 56, in <module>
    from lib.presets_config_handler import PresetsConfigHandler
ModuleNotFoundError: No module named 'lib.presets_config_handler'

I checked my zynthian-webconf.py against the one from the github-repo and they were not the same (even I tried a git pull before!). I tried to fixed it by:

git fetch --all
git reset --hard origin/master

After running zynthian-webconf.sh again I am now getting:

    from zyngine.zynthian_engine_mixer import *

… hmmm, ok. Going to /home/pi/zynthian-ui/zyngine and again

git fetch --all
git reset --hard origin/master

and running zynthian-webconf.sh again:

Now doing:

cd ../zynconf
git pull

… which seems to do something with some files. After that:

Ok. I think I will stop here. A seamless update to the latest stable without burning a new image seems not to work (for me).

I sometimes (often) have these problems when updating and I think this happens when the update process does not secure that all repositories have use the matching commit. It would be very nice if this process would be optimized. I know that this is not an easy task, but currently the only solution to avoid update probrems is using the Windows-Update-Process: just install from scratch…

Hi @C0d3man - Although I am not @jofemodo or @riban I’m going to ask a question and suggest a solution. Of course, you can ignore it if you wish.

How far behind the current stable was your V4 unit before the update? I think update has problems with large gaps between versions, particularly when there have been major changes.

You might be better off loading the latest image to a fresh sd card, then updating it with any changes-settings that you’ve made. And hopefully you can save those from the old system.

C0d3man · February 18, 2024, 8:53am

Hi @tunagenes,

thanks for your fast answer.

I cannot say for sure how far, but I try to keep up with the releases. I have three Zynthians running and the “band” Zynthian-v4 is always the lates one - I try “never to touch a running system”

This is the current state before updating:

Yes, for sure. But I thought the gap between my updates was not very big… sometimes I run into those problems even there are only small updates. For major releases I can understand that there may occure problems.

Yes - that’s the way I have to go nearly every 2nd update and that is frustrating with 3 Zynthians. As a precaution, I make a backup of the data via webconf, take a new SD and install the new software on it. I also like to keep the old one for a few days. As I said: for one Zynthian it’s fine, but with three it’s really exhausting.

I have just booted from the old SD card and am trying to make a backup via webconf. But it doesn’t work - the browser runs endlessly and doesn’t offer me anything to back up.

In addition, the variant with installing a new SD and importing the backup recently caused problems with Pianoteq, so I had to install PT again.

[EDIT] I just tried antoher browser for getting a backup before hard updating but backup says (after some seconds): 500: Internal Server Error. It’s getting frustrating. After two hours of spending time I end up with nothing - and I ONLY wanted to install the DYNAsAUR-808 and found a small bug…

Ok, now it’s getting strange:

New fresh actual image: Update via webconf. Last message was “webconf is restarted” but no webconf was running anymore - also not after reboot.

Is there a problem with the current webconf?

riban · February 18, 2024, 9:53am

Hi @C0d3man! Which image did you flash? Although the download might say “stable” the content of the zip has the date in the image title.

tunagenes · February 18, 2024, 9:56am

And I can report that webconf works with:
https://os.zynthian.org/2024-01-16-zynthianos-stable-2401.zip

piattica · February 18, 2024, 10:12am

I updated just now the system starting from stable 2401, updated 2 day ago: update does not end and now after restarting webconf does not work

Any suggestion to fix it?

piattica · February 18, 2024, 10:31am

If the solution is to flash the OS which is the correct one to download :

zynthianos-last-stable.zip

or

2024-01-16-zynthianos-stable-2401.zip ?

ToFF · February 18, 2024, 10:38am

yes, today installation of the latest stable version, software upgrade over webconfig and then zynthian.local - this web is not available

jofemodo · February 18, 2024, 10:50am

Hi @zynthianers!

You are right. There is an issue with the latest webconf update. A file was deleted by error. I tested but when commiting/pushing the changes, a file was deleted. Probably my fault. Sorry so much.

It’s now fixed, so you simply update and test.

Best regards!

piattica · February 18, 2024, 11:00am

It works. Thank you !

ToFF · February 18, 2024, 11:04am

I can only do update via webconfig so I…

piattica · February 18, 2024, 11:11am

update using ADMIN menu on Zynthian

ToFF · February 18, 2024, 11:13am

Ops, well, I’m not very smart.
But I found where update_zynthian.sh is hiding and did it from the ssh terminal

C0d3man · February 18, 2024, 11:38am

Hi @jofemodo

Now it works - also for my “band” Zynthian-v4.

Many thanks - you saved my sunday!!!
Thanks also to everyone who took part!
