An unofficial Debian Installer for Pinebook Pro

[acr]

Any thoughts what might be causing the following error during the kernel section of the Makefile?  Seems a strange place to break on an install command.

Code:

>>>> kernel

cat etc/default/u-boot.append | sudo tee -a /home/rock/src/pinebook-pro-debian-installer/sysimage/etc/default/u-boot > /dev/null
cat etc/initramfs-tools/modules.append | sudo tee -a /home/rock/src/pinebook-pro-debian-installer/sysimage/etc/initramfs-tools/modules > /dev/null
sudo install etc/initramfs-tools/conf.d/* /home/rock/src/pinebook-pro-debian-installer/sysimage/etc/initramfs-tools/conf.d/
