(This may be old hat to the Unix grognards out there, but...)
I was having trouble getting FUSE filesystems to mount (in my case, IPFS) in an LXC container, although the package seemed to install okay. Turns out something goes a mite glitchy when creating the FUSE device, and a quick:
sudo mknod /dev/fuse c 10 229
Clears the problem right up.
Hope this helps anyone else having this particular issue.
