I can successfully mount a drive on my Mac vi sshfs to several Ubuntu and Raspberry Pi machines (and then make it permanent with an entry in /etc/fstab), but when I upgraded one of them (an Odroid N2 with ARM architecture) to 20.04, I get the following:
/% sshfs RemoteMac:RemoteDir LocalDir
fuse: device not found, try 'modprobe fuse' first
And then when I enter
/% modprobe fuse
I get
modprobe: FATAL: Module fuse not found in directory /lib/modules/4.9.230-89
Not sure how to fix this.
