Template won't reinstall

Hi

I’m trying to reinstall a template but its not working. I tried the automatic way but got a errors. I emptied the cached packages (0 bytes). I rebooted, no good.

[terry@dom0 Desktop]$ sudo qubes-dom0-update --action=reinstall qubes-template-debian-10

I deleted the template. I tried the manual way

Tried it a couple of times. Notice that the failure point is different each time, like (4517 != 16384).

Is this an underlying hardware problem (disk is only 2 years old!), or am I missing something in the process?
