Comment 117 for bug 1021375

I see that many people say that killall nautilus works for them but it doesn't change anything for me. Perhaps someone could spell out the exact sequence of actions so that I can make sure that I am the problem?

What I am doing right now is
insert USB
try to paste something into it using nautilus (same with using terminal though), see that it's read only.
run killall nautilus in terminal.
(restart or not, I've tried both)
nautilus window disappears.
I try to copy something onto the USB again using Nautilus
still doesn't work.

What am I doing wrong?
I am working on 16.04.6 LTS

Thanks!
