I'm trying to generate a custom Ubuntu-Core OS for a network switch whitebox from DNI.
I'm building a custom kernel snap using the latest snapcraft, et. al. - I needed to patch a couple kernel files, but mostly the customization are config changes. The snap was built with confinement:strict, grade:devel I'm using ubuntu-image (Version 0.5+mvo10 Rev 17) to generate the image. The assertion file: type: model authority-id: TBD series: 16 brand-id: TBD model: canonical-pc-amd64 gadget: pc kernel: deltanetworks-l9032nxb-kernel architecture: amd64 timestamp: 2016-09-19T8:30:00-04:00 revision: 0 body-length: 0 The first problem is that once I boot the system and install the hello-world snap, then reboot, the snapd is unable to start up. So no more access to snaps. I've had this problem before and fixed it by using the ubuntu-core from the regular channel rather than the edge. However, when I leave out the '-c edge' from ubuntu-image, it fails trying to fetch the gadget. The second problem is that firstboot setup fails every time. I see this message in the syslog... error: cannot create state: state "/var/lib/snapd/state.json" already exists The third problem is I see 'Failed to start Notify bootloader that boot was successful'. I see this message in the syslog... error: cannot downgrade: snapd is too old for the current system state (patch level 4) Any guidance would be appreciated. Thanks, Mike
