Your suggested command reports Debian-12.0.0-and64-DVD-1.iso OK Followed by 20 lines of failed to read Debian-12.0.0-amd64-DVD-x.iso where x is in 2-20 These are I suppose lines from the full set of Debian DVD's So the DVD iso I burned and used to install Debian is OK Thank you, I'll know better next time On 6/23/23 19:17, DdB wrote:
