I told the WebUI to go ahead and do the 0.1.9 upgrade; it ended saying it failed and “Failed! Retry” red button showed up. I clicked it, nothing happened, and now it doesn’t seem Amplipi software is running.
I’ve SSH’d in but not sure what to look for/reinstall. Any guidance?
Oh no sorry to hear that! We definitely need a better procedure for handling failures like this. Without a lot of back and forth the simplest fix for this is to re-image your pi: re-imaging your AmpliPi
Before doing that you may want to copy your configuration file off of the pi. It is located in /home/pi/amplipi-dev/house.json.
Let us know if that works. We can also diagnose this by looking at the system logs.
Sorry for the delay, been a bit before I had a chance to get time to work on this. I’ll happily provide logs and see if you can diagnose what went wrong, I can live with my music on headphones for a bit =)
So for starters, house.json was empty; house.json.bak had what I needed.
What log files/etc do you want/need to poke at? I’d also be up for a Zoom session or anything to screenshare and let you poke around.
The update to 0.1.9 changes some things about logging, so I don’t know exactly where this is at. After the 0.1.9 update you should be able to access the system logs at http://amplipi.local:19531/entries. This may or may not be available to you. If it isn’t the same log can be saved over ssh then copied using scp.
Here’s what you need to do over ssh:
journalctl > log.txt
If you are using linux, this can be copied to your system using scp:
scp pi@amplipi.local:log.txt .
Otherwise you can use a program like winscp to copy the file off of the amplipi
You should now have a shiny log file. You may want to send that log over email to contact@micro-nova.com if it makes more sense.
Just to follow up on this now that it was resolved via email.
The problem was updating from 0.1.9 from the LMS Prerelease with LMS Server which had added 4 virtual sources.
Here was the relevant part of the log file:

For those of you that try this, the fix is to ssh in after the update fails delete the messed up config::
systemctl --user stop amplipi
cp amplipi-dev/house.json.bak old.house.json
rm amplipi-dev/house.json*
systemctl --user start amplipi
The old config will be saved in old.house.json. If you would like to recover that old config:
