The reason I sent that to you is because that is what I was going through yesterday and I came across your poset and it looked like the same issue and thought I would pass it along.
Also, what is the underlining OS Linux distro of your device. Mine is debian. I had to do this in root. So I had to do
su -
and login as root. I figure you are probably in root doing this. but just in case I thought I would add that.
I fixed the issue yesterday with @davidep 's help. Go ahead and read through the following post. The solution is close to the end. Here is the post you should read.
Hope it helps
