I have confused matters by using both the USB drive and the internal drive.
This morning my /dev has changed: now shows sg1 as well as sg0; also now shows sr0 as well as links from cdrom,cdrw,dvd and dvdrw to sr0.
Eject worked on the internal drive with no disk in it. But with a data disk in it I can't mount it or eject it:
Code:
user@debian:~$ mount /media/cdrom
mount: no medium found on /dev/sr0
user@debian:~$ mount /media/cdrom /mnt
mount: only root can do that
user@debian:~$ sudo mount /media/cdrom /mnt
mount: /media/cdrom0 is not a block device
user@debian:~$ sudo mount /dev/sr0 /mnt
mount: no medium found on /dev/sr0
user@debian:~$ eject
eject: unable to eject, last error: Inappropriate ioctl for device
Code:
user@debian:/dev$ ll |grep sr0
lrwxrwxrwx 1 root root 3 Nov 24 11:32 cdrom -> sr0
lrwxrwxrwx 1 root root 3 Nov 24 11:32 cdrw -> sr0
lrwxrwxrwx 1 root root 3 Nov 24 11:32 dvd -> sr0
brw-rw----+ 1 root cdrom 11, 0 Nov 24 11:32 sr0

After the above I was now able to boot from a disk in the internal drive. It began to install Puppy linux to RAM but froze, so I had to shutdown. Now upon rebooting Debian Stretch /dev no longer has sr0 and links.
Code:
user@debian:~$ cat /proc/sys/dev/cdrom/info
cat: /proc/sys/dev/cdrom/info: No such file or director

i'm beginning to suspect that your thread title is misleading, and your problems do not stem from an upgrade and even the mysteriously disappearing cd rom drive is just a symptom of something bigger - hardware trouble?
