Thanks for your reply.
Today I tried to fix the last working release but it didn’t work. The behaviour is the same : the release is downloaded on the device and the host OS tries to start it but it stops because of a SIGTERM signal being received. See the following screenshot from the host with the command dmesg.
I tried to deploy an example of a small application with electron and resin that displays a unicorn on the screen and it works !
When I tried to deploy a minimal Dockerfile with only FROM resin/up-board-buildpack-deps:stretch , ENV INITSYSTEM on and CMD ["echo", "balena" ], it didn’t work. But in the previous small app, the FROM image is the same and it uses INITSYSTEM there too.
So, I don’t understand what I missed.
I grant support access and the device’s URL is https://9abde87abc010c2ab533c87fbc0013cf.balena-devices.com/
Thank you.
