Try some other distro
>to make sure you have a good copy from your download?
Have you ever tried to repair a "bad" zip?
If download is bad , xzcat or zcat will 'error out'
Or you can test, xz -t image.xz (indeed, isos should be checked. a good reason to 'zip' them)
And, there is a 'gotcha', if SD and emmc have same distro,
there may well be identical, duplicate fslabels or UUID's
sudo blkid,, this is NOT a good idea if used in fstab or extlinux
