Hi @ll,

I just updated my Zynthian (2020-04-23-zynthianos-buster-lite-1.0.0) after a moth and got some problems. Here are my fixes - unless I caused these problems myself.

First problem:

May 23 10:35:57 zynthian startx[462]:   File "/home/pi/zynthian-ui/zyngui/__init__.py", line 53, in <
May 23 10:35:57 zynthian startx[462]:     from zyngui.zynthian_gui_audio_recorder import zynthian_gui

May 23 10:35:58 zynthian startx[462]:   Building XImage...done

Solution: apt install python3-mutagen

Second problem:

May 23 10:37:52 zynthian startx[458]:   File "/home/pi/zynthian-ui/zyngui/zynthian_gui_stepsequencer.

May 23 10:37:53 zynthian startx[458]:   Merging...done
May 23 10:37:53 zynthian startx[458]:   Building XImage...done

Solution: cd /zynthian/zynthian-ui/zynseq && ./build.sh

Hi @C0d3man!

The raspbian repo version of mutagen don’t work because it has not wave file support yet!

There is a recipe for installing mutagen from repo code, and it should been installed when updating. If it didn’t succeed, we should investigate what the problem is. Perhaps simply updating again solves the problem…

Please, uninstall the mutagen repo-version and try updating again. If not, try to figure what is failing with the updating process …

Thanks a lot,

Hi @jofemodo,

ok - my fault: I forgot to rebase my (dev) zynthian-sys repo…

I deinstalled python3-mutagen and updated again: Now it works!
