Upstart to automount USB in Ubuntu Server 20.04
usbmount is the tool to automatically mount and unmount USB mass storage devices.
You can install it like so:
Run in the terminal:
sudo apt update
Then run:
sudo apt install usbmount
Then run:
sudo systemctl restart udev
Done. When a USB storage device is connected, it will be mounted under /media/usb[0-7]
and it will be unmounted when disconnected.
