Can't mount encfs-encrypted volume using Linux encfs

[kkeane]

This is a companion to #1073 .

The Linux version of encfs does not work on bash on Ubuntu on Windows. When attempting to mount an encrypted volume, an fusermount issue prevents mounting.

• Expected results
  kkeane@LENOVO4G:$ mkdir -p ./plaintextdir
  kkeane@LENOVO4G:$ /usr/bin/encfs ./encrypteddir ./plaintextdir
  EncFS Password:
  kkeane@LENOVO4G:~$ ls ./plaintextdir
  
• Actual results (with terminal output if applicable)
  (Note: bin/kpmount is a script that automates the encfs call with the same paramters as provided above)

kkeane@LENOVO4G:~$ bin/kpmount
EncFS Password:
fuse: device not found, try 'modprobe fuse' first
fuse failed. Common problems:

• fuse kernel module not installed (modprobe fuse)
• invalid options -- see usage message
  kkeane@LENOVO4G:$
  kkeane@LENOVO4G:$ sudo modprobe fuse
  sudo: unable to resolve host LENOVO4G
  [sudo] password for kkeane:
  modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file '/lib/modules/3.4.0+/modules.dep.bin'

• Steps / All commands required to reproduce the error from a brand new installation
  cd
  mkdir ./plaintextdir
  create an encfs-encrypted directory on another system
  copy encrypted directory to ./encrypteddir
• Strace of the failing command
  N/A
• Required packages and commands to install
  encfs
  fusermount (which can't work since it is a kernel module).

Thanks for posting the follow-up ticket! Just for completeness, this presumably has the same root cause as #17 and #412 , among others.

I really hope FUSE/CUSE is given consideration after the obvious low-hanging syscall surface stuff is done. Given that kernel modules in the native sense can't ever be a thing on WSL, and open-source is a non-starter for reasons, FUSE is one way out of WSL pico-process jail. There's a User Voice here that isn't getting enough love.

Dupe of #17 and others like Adam indicated.
