I installed the Debian 9 from a Debian live amd64 image I downloaded
today.  Everything works great, but I can't su to apt-get anything new.

theo@debian:~$ su
Password:
su: Authentication failure

I have reinstalled twice, being super careful to get the password right,
etc.  But it simply doesn't seem to work on this version.  Anyone else
seeing this problem?

Thanks,
Daniel

Assuming sudo is working properly, try resetting the root password:

$ sudo passwd root

Hi,

I have seen this issue too.

I have not had time to look into this issue, but believe it maybe
related to a known issue No. 3 on:

https://cdimage.debian.org/debian-cd/9.0.1-live/amd64/iso-hybrid/

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864955

After the live 9.0.0 ISO failed early in install and now the 'su'
issue. This raises questions about the testing and QA of of the live
ISO images, both pre release and at release time that need to be
discussed and addressed in-order to avoid them in the future.

Regards

Phil
