Cannot copy to USB - every USB stick is read only (16.04)
My head hurts a little from all this, but hey turned out to be this bug. It's a shame to see the community take such a setback from the dismissal of Unity, and while they start over the giants like Microsoft and OS continue to progress down the road.
killall nautilus
Worked for me.
I found this info. Try this: How to fix read only USB pen drive in Ubuntu. I do not know why every USB stick would be read-only. Hope it helps anyway.
This is how I fixed the permissions of my pen drive that 'suddenly' became readonly.
Switch to super user with:
sudo su -
Find in which directory the USB drive has been mounted by running:
df -Th
You should get a list of drives and your USB drive should be listed as:
/dev/sda1 fuseblk 15G 65M 15G 1% /media/someuser/myUsbDrive
Change the permissions of your USB pen drive (located at
/dev/sda1
) with:
find /dev/sda1 -type f -exec chmod 666 {} \;
or with
find /dev/sda1 -type f -exec chmod 644 {} \;
Now your drive should be writable.
If the above doesn't work then change the permissions of the directories to make them writable:
find /dev/sda1 -type d -exec chmod 755 {} \;
