Following this guide to install Unbound for DNS purposes and I have ran in to a problem with the following cmd:

sudo mount --bind -n /dev/log /etc/unbound/dev/log

sudo mount --bind -n /dev/random /etc/unbound/dev/random

I get the following sysntax error:

root@pc:/etc/unbound# mount(2) system call failed: Not a directory.

I have used the chown cmd, and the chmod cmd thinking it may be an issue with permissions, and it didn't help.

I have searched for awhile on the net for someone who has had this problem yet I've seen no others.

OS is Ubuntu 18.04.04

Thanks for the help in advance
