mount dev/sr0

Ola everybody
I have same problem to mount /dev/sr0 on my system.
I m using Ubuntu 16.4
 /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=58d59378-547f-4b69-91b7-d5262f59ffa1 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
