UPDATE: I had already added vers=1.0 to the fstab file, and I had rebooted at least twice. I rebooted again without making and changes other than unmounting the drive in Files, and it's now working. I'm not sure how tenuous this link is, but hopefully this fixed the issue.

I've changed strategies. Since the permissions issue was obviously too complex to tackle with my limited ability to explain the problem, I decided to simply use my router's Samba hosting and plug the hard drive in there. SUCCESS! I can access the samba share using smbclient from the command line, and I can access it from Gnome in "Files." However, when I try to use CIFS to create a permanent mount to the Samba drive using the EXACT. SAME. INFORMATION. it says, "mount error(112): Host is down." This is the most frustrating thing I've experienced in the world of computing. I just want to share my damn external drive so that I can use Plex/Kodi/etc. to watch my decades of media on my devices in my house. I'm using Ubuntu 18.04. It shouldn't be this complicated. Any help would be greatly appreciated.

I am running Ubuntu 18.04. I'm new to Linux, but I'm pretty good at reading various guides. Unfortunately, I've tried so many solutions to this problem that I'm not even sure where I am in solving the issue at this point. I have successfully setup a Samba share on my Ubuntu machine, but when I open the folder on my Mac, I cannot do anything other than see the folders and open the files. Trying to do otherwise results in an "Operation not permitted" error on OSX. I know this must be a permissions issue, but I have attempted changing ownership and permissions to wide open in an effort to force the ability to add files to the external hard drive on the Ubuntu machine from my MacBook, and I'm having no luck. Like I said...I'm new to Linux, so I don't even know where to begin regarding logs, etc. Any guidance--even if it's "completely remove Samba and start over"--would be appreciated. Please bear with me, as I've explained the issue as much as I currently know how to explain it.
