Some distributions do not name the fusermount directory as fusermount3 which rclone needs in certain circumstances (mounting as daemon).  To fix this, create a simlink to the fusermount directory in path

sudo ln -s /bin/fusermount /bin/fusermount3

Thats it, rclone will now mount without a fuse error.  you may need to alter the origin location in your environment to reflect where fusermount lives.
