First change the last entry to UUID=And-put-the-long-uuid-number-here.
Second, Do you have a folder in the /mnt directory with that name?
If not, make one, or better yet, make one with an easier name.
Thirdly, after the mountpoint(/mnt/#####), you need a file system type, in the case I think it's EXT4.
sudo mkdir /mnt/foldername-you-like
I'm sure there are other things that need to be done, but that's the basics I got from a simple look.
/dev/disk/by-uuid/e8982b22-1ef3-436b-b4fc-a64255b3f582 /mnt/e8982b22-1ef3-436b-b4fc-a64255b3f582 auto nosuid,nodev,nofail,x-gvfs-show 0 0
Something like that.
UUID=e8982b22-1ef3-436b-b4fc-a64255b3f582 /mnt/some-folder-name-here ext4 auto nosuid,nodev,nofail,x-gvfs-show 0 0
