@gerald: right, there is no way to protect you from turning the device into a brick if this step goes wrong (unlike kernel or rootfs we can not roll back the bootloader) note that the gadget snap from edge will not have a working dtb for the old kernel which will likely make you end up with an unbootable device. sadly on the pi the dtb gets loaded by the binary blob which is why we can not just use it from the kernel snap (which would fix this problem). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1647936 Title: Raspberry Pi 3: a small rainbow square on the top right of screen Status in Snappy: Fix Committed Status in linux package in Ubuntu: Invalid Bug description: I'm working on the WD/nextcloud project, and found this issue Download the UC16 for Raspberry Pi 3 from http://releases.ubuntu.com/ubuntu-core/16/ubuntu-core-16-pi3.img.xz unxz , dd the image to sd card and boot up the system.
