It was recommended that I update to Buster.
I started with Debian 9.1.0 installed from purchased DVD1.

I edited sources.list to access online repository.
I then followed the instructions at
[linuxconfig.org/how-to-upgrade-debian-9-stretch-to-debian-10-buster]
as it had everything conveniently shown.
That guide misses so crucial details and so barebone that it even feels
wrong.
I mean, there's the obligatory "backup your system first"?
*ROFL* I am a graduate of School of Hard Knocks, Slow Learner division.
I have a system on a flash drive backup.
I have TWO copies of my /home partition.
<Tips hat>
I installed stretch to another partition which I'm using now.
Is the Buster install repairable?
Depends. I'd start with chrooting into this "another partition" and
doing like something like this:
I've never used chroot - I wasn't clear on what happened on current system and what went on in the system chrooted to.
Are you saying to boot the "Buster" system and chroot into the known good Stretch system?
No, stay in stretch.
1) Become root.
2) Mount buster installation in, say, /mnt.
3) Classic chroot sequence:
mount -o bind /proc /mnt/proc
mount -o bind /sys /mnt/sys
mount -o bind /dev /mnt/dev
chroot /mnt /bin/bash
# You're in chroot now
# Do not leave until instructed
4) Prevent buster services from running:
cat > /usr/sbin/policy-rc.d << EOF
echo All rc operations are disabled by policy: \$1 \$2
exit 101
EOF
chmod 754 /usr/sbin/policy-rc.d
5) Hard part starts here:
dpkg --configure -a
apt update
apt upgrade -s
6) Cleanup:
rm -f /usr/sbin/policy-rc.d
exit
# You left chroot
7) Finally:
umount -l /mnt/proc
umount -l /mnt/sys
umount -l /mnt/dev
umount -l /mnt
