- The font will be very tiny so get a magnifier.
- Wifi installation will fail due to non-free firmware, skip setup.
- Mirror selection will fail since no network, skip too.
- On another USB drive (or the same one after reformatting), download the Wifi firmware, I used firmware-atheros_20180518-1_all.deb.
- Mount the USB drive, find the firmware, and run (as root)
dpkg -i firmware-atheros_20180518-1_all.deb
. - Update
/etc/apt/sources.list
as needed, making sure to addnon-free
. - Confirm Wifi is working,
apt update
andapt full-upgrade

To make a bootable image From macOS, assuming the USB drive is disk2
:
sudo diskutil unmountdisk /dev/disk2
sudo dd if=./IMAGE.iso of=/dev/disk2 bs=1m
# or if coreutils are installed:
sudo gdd if=./IMAGE.iso of=/dev/disk2 bs=1000000 status=progress
Another option is to use Boot Camp Assistant to make the image.
To restore a bootable USB drive from macOS:
sudo fdisk -e /dev/disk2
# interactive prompt
auto dos
quit
Then format the drive.
