[This guide][intel-nuc] describes how to install Ubuntu Core on Intel NUC using two USB flash drives.

Here are a few alternative options to remove the reliance on a second USB flash drive:

Download the image on live Ubuntu

This is self explained. Boot into the live Ubuntu and download the image. Flash it according to the [official instructions][intel-nuc].

This is not always practical:

• We may need to reuse that image without downloading it every time
• We may need to use a custom-built image that isn't available online

Debugging an Ubuntu Core installation with QEMU

The Ubuntu Core installation fails if one of the required seeded snaps fail to start. When a required snap fails, the system starts shutting down, snapd stops, and we end up with the following strange error:

cannot obtain system details: cannot communicate with server: Get http://localhost/v2/system-info: dial unix /run/snapd.socket: connect: connection refused

or

/usr/share/subiquity/console-conf-wrapper: line 32: snap: command not found
