Bug Description

First time I use an USB drive since I updated to 12.04 and I found a really annoying bug on Nautilus. Nautilus claims that the destination drive is read-only when in fact it is not.

How to reproduce:

1. Connect a USB stick drive to your competer.
2. The USB will appear in the desktop.
3. Open two Nautilus windows one in your home folder, other in the USB stick drive.
4. Select any file from your home folder (small enough to fit the free space in the USB drive)
5. Drag the file and drop it in the USB drive window.

-- Nautilus will say that it cannot copy the file because the destination is read ony --

If you try the copy the same file with the terminal you will see that the file is copied without problem, other programs like gedit or LibreOffice can write in the usb stick drive just fine.

It is not a problem with the USB stick, as shown here:

[ 6234.212740] sd 8:0:0:0: [sdb] Attached SCSI removable disk

The permisions on the removable drive are set correctly:

There is enough free space in the drive:

But nautilus just dennies to copy the file claming that the destination is read only, when it is not.

I tested it with two different USB sticks in two different computers running Ubuntu 12.04 and the same result.

I came across patched Nautilus from SoluOS project, installed it in few easy steps described here:

And now Nautilus work OK :) So it's one of their patches, which solves the problem :-)

Dac Chartrand (conner-bw) wrote :

I'ts the same problem for me. I'm using a USB hard drive (Fantom Drives, Green Drive, 1TB)

I even formatted the drive using Ubuntu 12.04 itself. That is, in Unity Launcher on leftside, I right-clicked the drive icon and selected Format. I did tests using both EXT4 and FAT32. Same results.

As I type this Ubuntu 12.04 "Backup" has no problems writing to the drive. I have no problem writing to the drive in the Terminal. If I open Gedit and save to the drive, no problem...

But, anything I try in Nautilus (Create New Folder, Drag & Drop Copy) gives the error: "The destination is read-only."

In one laptop i use the 1:3.4.2-0ubuntu4 version and no problem at all, otherwise another 2 machines win 1:3.4.2-0ubuntu5 version is affected by the bug.

ah, forgot: ctrl-v and ctrl-c don't work under nautilus. gksu nautilus didn't help.

One more person with this read-only problem :-(

When I put a SD Card into the slot in my laptop Nautilus opens the SD Card, but I also get the problem: The destination is read-only :-(

In a terminal everything works fine.

When I run sudo nautilus in the termnal everything also works fine and I can write to the SC Card - but why not when I'm running Nautilus as normal user :-(

Permissions look also fine to me:

I need to stay on 12.04 LTS (!)
FWIW I found that restarting the machine and reinserting the usb stick, gave me a normally functional usb with nautilus.
Another fix was to install an alternative file manager Thunar, and make use of this while the problem occurred.

This problem affects me on Ubuntu 13.04 64-bit, running nautilus 3.6.3 from default repositories. This is a fresh install with all available updates installed.
All USB drives show "Error while copying to "[name of drive]." The destination is read-only."

Tested with three working USB sticks, all formatted FAT-32 via Gparted. Able to use touch, cp, mv, mkdir via terminal with no problems. Simply unable to create folders, drag files, or copy/paste files though nautilus.

Here is the terminal output from running 'mount' with one of these USB drives plugged in, after receiving error message. Note, USB is last disk listed, /dev/sdh, mounted under /media/mike/SanDisk:

I can have write access only when nautilus is launched using sudo from a terminal.

Christophe Viallon (cviallon) wrote :

Well, I found a solution.
1. I renamed the /home/[my-username]/.config directory as /.config.old
2. After logout and new login, a new /.config directory is generated.
3. I replaced the old /.config.old/nautilus directory by the newly generated /.config/nautilus
4. /.config erased.
5. /.config.old renamed as /.config again
5. Logout and new login => problem solved.

Thanks, Christophe, but we would like to know the rationale behind your workaround, in order to better know why the bug happens at the first place.

Had the same issue on 13.04. Trick from #22 also helped. The only difference between two configs is that the bad config has an extra line in the middle of it:

Is anybody has found what triggers it ?

The very same problem exists on Mint 15 (based on 13.04) and Thunar 1.6.2.
I actually run Nautilus to work around the problem and copy the files.
The problem might be in lower levels.

Just happened to me all of a sudden (eg, have not observed this problem on 12.04 or 13.04 until today, but haven't used a USB stick for 2+ weeks). Unity desktop; Files 3.6.3 (whatever that is) produces a popup stating that target is read-only, which it isn't, of course. The config file identified in post #22 contains the line indicated there...
; (gtk_accel_path "<Actions>/ExtensionsMenuGroup/DejaDupNautilusExtension::restore_missing_item" "")
But it looks as though it is supposed to be there.
Would be happy to edit a defective line out, but is anyone sure which it is ?

I can copy files using Terminal as normal user. But with nautilus, it giving me "is read only" error.

Johann Gail (johann-gail) wrote :

I have the read-only bug under a slightly different condition: Its not a external USB-Stick but a remounted partition.

For security reasons I have an archive partition which is mounted read-only at startup of the notebook. When I mount the partition afterwards in readwrite-mode then nautilus tells me, the partition is still read-only. But all other tools, commandline etc. works fine.

So it seems to me, this bug has something to do with in-memory cached directory information in nautilus. Maybe this information gets cleared during logout/login, so it is not the observed line in the .config but the process of relogon which solves this problem?

I have this effect since at least two years and with different versions of ubuntu. For sure with 12.04, 13.04, 13.10 and all updates between them. For me this bug is allways fully reproducible.

I to have the same problem!
I have tried 2 diferent USB sticks & nothing can be saved to them. Either by drag & drop or saving from a text editor (JuffEd & Gedit) or even OpenOfice.
One of the USB sticks did let me moove a file when I firs got it but it stoped after I plged it into my Android.
I can open the USB sticks in "Windows!" & chaing the permissions.
But I am completly locked out with Ubuntu.
Is pluging the USB sticks into other OS's leaving a cooky that Ubuntu is objecting to?
Have fun.

The other interesting thing is the same usb drive used to work fine with nautilus till before I made a bootable disk on the usb device using dd. I tried coping the initial 20MB from another usb. But the "read only" error persists.

I appear to be having the same issue as SergeiS & tonysonney under 14.04,
file system permissions are correct and cp works fine from the command line for one of my USB hard drives, but drive consistently shows as 'Owner: root' in Nautilus - even though mount options are identical to an automounted SATA drive that shows as 'Owner: me'

Other USB devices, (flash drive, HD from a different manufacturer) mount with correct Ownership in nautilus.. (also, i noticed everything that mounts correctly has a little icon in the media folder - a thumb-drive, internal disk icon, etc. while the badly behaving "root" media device does not have a little icon on the folder)

remounting per comment #20 (sudo mount -o remount,rw /media/<mount point>) did not work with nautilus 3.10.1-0ubuntu9.3 on 14.04

I wonder is this related to traversing symlinks to the mount point?

I also have the same problem on 14.04, however I'm using Nemo and not nautilus.

I too have the nautilus read-only misbehavior on the very latest 12.04LTS (x86_64) system and have the following observations, including a simple-enough workaround since running into this problem quite a while back....

I can cause the false read-only behavior on demand by first inserting a read-only USB flash such as a camera's Secure Digital card with the "lock" switch thrown, via an SD card reader. But after removing/unmounting that read-only SD card, *every* subsequent insertion of a normally-writable USB flash drive then gets the above-reported symptoms: its considered read-only by nautilus yet a "cp" command from the shell to the USB media works fine which shows the system mounted it correctly for writing.

As I believe someone mentioned earlier, it must be that the nautilus state is contaminated/broken under some scenarios. My intentional read-only flash drive method is just one solid way to cause that broken behavior "hangover". So my workaround is....

When I encounter this false read-only, I simply unmount/remove the removable device(s), close any windows using nautilus, and then I do a "killall nautilus" from the shell (I always see a non-window nautilus whose parent is pid 1 with my user id, presumably this is the thing with the broken state that I kill). After that, reinserting the very USB drive which falsely received the read-only error will now work properly. I can drag things onto the drive using the fresh instance of nautilus that is launched..

Its a shame that after more than 2 years, on a claimed LTS system, I have yet to see even a "we aren't going to bother fixing this one" response from the Ubuntu folks on this bug report. Its not been closed or marked as a duplicate, its still marked "unassigned". Makes me question why I've been recommending Ubuntu LTS releases at all to my companies for production use....

In 14.10 this problem still exists.

I just had this problem occur again, I am using 12.04 (still). I also got it tp work correctly, here is what worked for me (YMMV). I am not sure all these step are required, but the combination fixed my problem.

1- sudo chmod 755 /media (this was recommended with -R option, but I did not want that as my raid is mounted under /media)
2- cd
3- mv .config/nautilus .config/nautilus.bak
(the net effect is a new nautilus desktop file is created, for me the delta was deletion of "nautilus-icon-view-auto-layout=true" and a change to the nautilus-icon-view-layout-timestamp value)
4- remove media if it happens to be in
5- logout
6- login
7- insert media and test

Good luck.

I just installed Ubuntu 15.04 RTM and almost three years after this ticket has been opened this problem still persists. It' very hard to use the OS when it can't properly handle such important thing as the work with USB-drives.

There is no such issue with Fedora 21, which is also based on Nautilus file manager.

Andrea Gamba (andrea-gamba) wrote :

The problem is still there.

How is it possible after so many years?

It is a serious usability problem.

Mike (pub-mikeb) wrote :

For me it's actually not an «usability problem» but is a stop-bug, which prevents the usage of Ubuntu at all.
The usage of USB-stick, flash-drive is daily task for me and I can't imagine that each time I have to use it the OS will cause the problems and will prevent the usage.

Please, fix it ASAP, it's much more important than any other features, like Unity 8/9/10, etc.
