I guess you could say that I'm a slightly educated noob (I know, a little knowledge is a dangerous thing).

My drive worked fine in Mint 17.3, but I am now running Lubuntu 16.04 and my DVD drive has not worked yet. I have tried multiple CDs and DVDs; music, data, and blanks.

lsblk -f returns:

sr0          

cat /dev/sr0 returns:

cat: /dev/sr0: No medium found

So I tried lshw and got this:

*-scsi

     physical id: 2

     logical name: scsi0

     capabilities: emulated

    *-cdrom

         description: DVD-RAM writer

         logical name: /dev/dvd

         logical name: /dev/dvdrw

         logical name: /dev/sr0

         serial: [

         capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram

         configuration: ansiversion=5 status=nodisc

And then there's this:

$ mkdir ~/dvd | sudo mount /dev/sr0 ~/dvd

mount: no medium found on /dev/sr0

I'm pretty much grasping at straws at this point. So, what now?

Update on info: I can locate it in Disks with no problem, but it shows no media when I have a DVD in the drive. I have already cleaned the lens, but that was never an issue as it worked fine before I installed Lubuntu 16.04

Actually your system does find the drive and identify it properly as well, as a Sony DVD RW AW-G540A. Your output provided indicates that the difficulty is in reading from the drive which the system is convinced is empty as you mentioned. The root cause is likely a failed laser (since you've cleaned the lens). The device if it's repairable at all isn't worth the cost to repair. I recommend replacement of either the drive or the entire laptop (if the budget can handle it) considering the age.

Command line wodim worked for me when nothing else would:
