Every USB stick I plug in is read-only and I cannot copy files to it.

Here's what I've tried so far.

1. I've formated each one to either FAT32 or NTFS, quick and detailed
   format in Disks and GParted


2. I've used GParted to format the stick and recreate the msdos
   partition table layout. The device mounts fine, but won't copy files


3. I've tried using other USBs that already have files.


4. I've tried to unmount, remount:
   
   

   
   

   sudo chmod 777 /media/USER/USB_LABEL and
   sudo mount -o remount,rw '/media/gaj/Working'

   
   

   
   


5. I've changed permissions on all my media


6. 
   

   There are no panic messsages when pluging in the USB:

   
   
   

   
   

   dmesg | grep -i panic

   
   

   
   


7. These are the dmesg log messages after pluging in and trying to copy to USB ( is the brand)

8. I run fsck on my USB device /dev/sdb1, which finds some "dirt" and fixes it, but again nothing changes.

Can anyone help me before I smash my computer into pieces and move to fedora?

I found this info. Try this: http://sharadchhetri.com/2013/12/19/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.

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.

You should try formatting it with the Ext4 partition format. That should let Ubuntu at least read and write to the USB drive correctly.

This is how I fixed the permissions of my pen drive that 'suddenly' became readonly.

1. Switch to super user with:
   sudo su -



2. 
   

   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

   
   


3. 
   

   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 ;

For a FAT formatted drive the following should work.

Mounting this way in Ubuntu 18.10 is now deprecated, but still works. With a spot of luck your external drive will be mounted as the current user. Please note though that sdb1 may not be the name of your drive.

gvfs-mount -d /dev/sdb1
