I'm using lubuntu, but still think it's very similar to ubuntu. I need to install exfat-nofuse as my NAS has exfat format.
I followed these instructions on this post: https://askubuntu.com/a/400946/313828
Everything was fine until the last code:
sudo modprobe exfat_fs
All I get is this message: modprobe: FATAL: Module exfat_fs not found. Same result if I use exfat without '_fs'
