Installing distro iso images

[Paul Gear]

Rob is correct - recent Ubuntu ISO images should be directly bootable
when dded to a USB flash drive.  This has been the case since at least
16.04, probably earlier, for at least amd64 images (I'd presume i386
images, too, but amd64 are the only ones I use, so I can't vouch for
them personally).

Geoffrey, if you open a terminal and run "sudo apt-get update && sudo
apt-get dist-upgrade -s", what is the output?

Regards,
Paul
