Original GitHub issue: https://github.com/netbootxyz/netboot.xyz/issues/918

Booting from the hosted netboot.xyz instance and attempting to load the Ubuntu or PopOS 20.04 Live Images lead to failure, and dropping into an initramfs shell.

It seems to be that curl is failing to grab the squashfs image with the error message:

curl: (23) Failed writing body (<varying number between boots> != 16384)

Screenshot attached of attempted boot to Ubuntu 20.04 Live Image.

How much ram you have on that setup?
Squashfs images are stored in a ramdisk which is half of the available memory on the machine.
Those squashes are big too, prob need a machine with 8 gigs min to support booting these Live CDs.

I was originally attempting on a VM with 4GB of RAM. Bumping it up to 8GB got them both to work, thanks!
