I know someone had already asked a question about mounting HFS+ drives on Ubuntu 16.04, but it was for a server edition. My workstation is not a server. I have however tried every solution proposed to the HFS problem that I found anywhere online. I did install the linux-image-extra:
suncrushr:/$ sudo apt-get install linux-image-extra-$(uname -r)

linux-image-extra-4.10.0-37-generic is already the newest version (4.10.0-37.41~16.04.1).
linux-image-extra-4.10.0-37-generic set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.
When I check if the module exists I don't get any errors, it just returns to the command line:
suncrushr:/$ modprobe hfsplus
suncrushr:/$
so I take it, the module does indeed exist. However when I check if I have the filesystem listed, I get nothing useful:
suncrushr:/$ cat /proc/filesystems | grep hfs
squashfs
and of course when I try to mount an HFS drive I get an error about unknown filesystem. So it's like installed and not installed at the same time. Why do I bother? I was a Mac user for 15 years and that after having lived in SGI Origin world for a good long while and the nature of my research projects leads to a proliferation of external drives. I am fairly new to Linux itself even though I haven't used Windows since Windows for Workgroups. I got me a monster Linux laptop after I killed my MacbookPro. What a breath of fresh air. I was seriously getting sick of MacOS wiping out my /usr/local/ and all my compilers every time my arm was twisted into an upgrade but now I have a bunch of data orphaned on those external HFS drives. Turning journaling off doesn't help. mount still complains that the filesystem is unknown.
Any other ideas?
