I ran the update software command from the web interface, and now I get an error screen upon boot. This is a V2 unit, never had an issue before.
zynthian_update.txt (3.8 KB)
The last line is “Running Flag Actions from ‘/zynthian/zynthian-sys/scripts/update_zynthian.sh’…”
I can ssh into the unit and do
systemctl stop zynthian
systemctl start zynthian
but it does not resolve the problem. I do not see a zynthian_update_sys.sh anywhere.
Does it still say your machine is configured as a V2?
I just stopped zynthian using the ssh interface, and ran update_zynthian.sh from the terminal, and I do see one error in the trace:
Updating zynthian-sys …

Yes, but does the webconfig say your machine is still configured to V2 or did it get set to something else?
It doesn’t say specifically, but it does have message in the log that indicates it sees it as v2, like
Custom Config /zynthian/zynthian-sys/custom/display/PiScreen 3.5 (v2) …
the boot error does not show a version:
You can find out more if you visit the webconf
I suspect the update has somehow changed the configuration of the zynthian.
Ok, is there anything in the UI log under > Interface?
Yes, I get this, sorry about the length:

Then it repeats starting at the "PNG file: " file
ssh back in and issue apt install python3-evdev and see if that solves it after a reboot.
Aha, I got it!

After a google, I did
root@zynthian:/home/pi/zynthian-ui/zyngui# systemctl unmask packagekit.service
Removed /etc/systemd/system/packagekit.service.
root@zynthian:/home/pi/zynthian-ui/zyngui# systemctl start packagekit.service
And it started working again! Thanks @Baggypants for all of your help, I really appreciate it!
I don’t know what happened that meant evdev wasn’t installed as it is needed for the calibration, it might mean other stuff has gone awry. I’d recommend backing up snapshots and stuff and starting again from a recent image.
@mepex, your base image is too old. You should download and burn the latest stable one:
After first boot, don’t forget to config your v2 kit from the webconf interface.
