It's Superuser shell actually, not Supervisor/Executive one. > I created a directory called /media/myusb and issued the following command to > mount the USB stick to it: > mount /dev/sdb1 /media/myusb > > The error message is: > mount: /media/myusb: /dev/sdb1 already mounted or mount point busy Something has mounted your device elsewhere already. A usual thing with the modern desktop environments. Check the output of "mount" and "df -Th" and /dev/sdb1 will probably be there. I'd like to see the output of these commands too, btw. > Below are the results of cat /etc/fstab If these are the full contents of /etc/fstab, it's incorrect. In addition to the mountpoint you should specify a block device (or its equivalent), filesystem type, mount points, dump/pass and that's the least. I.e. this line is wrong: /media/myusb This line is correct: /dev/sdb1 /media/usb auto defaults,nofail 0 0 "nofail" is really needed for removable devices, because whoever designed systemd made an "interesting" decision to halt the boot process (i.e. host is inaccessible by network, console access only) even if a single filesystem mentioned in fstab fails to mount. You may want to add "noauto" as well, see fstab(5). Reco
