fusermount: mount failed: No such device about winfuse HOT 5 CLOSED

This error is returned by the libfuse fusermount program in do_mount. This means that the libfuse fusermount program was not replaced by the winfuse version (which knows how to mount file systems in WSL1).

Can you please try the following commands for me:

• ls -l /dev/fuse
• ls -l /usr/bin/fusermount*

Here is output from my local system:

(The fusermount*.~*~ files can be ignored as they are backups of the original libfuse fusermount and fusermount3 programs.)

It appears that you have the correct versions of fusermount and fusermount3 installed (they are both 34040 bytes as in my system and you also have the fusermount-helper.exe Windows program).

However the "fusermount: mount failed" message is never output by the fusermount that ships with WinFuse. This suggests that libfuse executes its own fusermount program, which is the "wrong" one for WSL1.

Given that fusermount is usually installed in /usr/bin I am uncertain how this would be possible. Do you have an unusual installation of FUSE on your machine?

Please also note that my tests have been against Ubuntu 20.04. As far as I can remember Ubuntu 18.04 did not include FUSE3 in its packages, which means that it does not have the latest version of SSHFS against which my tests were done.

Hi, I got the same output as yours. Can you please share how you fix the problem. I am using Ubuntu 20.04. In my case the error message from sshfs is fuse: device not found, try 'modprobe fuse' first though. Similar error when using davfs, which says it cannot open fuse device when /dev/fuse is already created.

from winfuse.

Hi I had the same problem too. I ran sshfs without sudo and it worked.
