Error _instance not declared in scope (DragonOS install)

[alphafox02]

A couple things I'd like to share.

I took the latest DragonOS Pi64 image and ran the installer. During the apt upgrade a new kernel was pulled in. Users should consider if this happens pay attention to the cariboulite build process. You'll notice everything is built against the currently installed/running kernel. Will likely be an issue when you reboot.

Additionally, this occurs during the build process.
