For some reason I can't change the file permissions of my var/www folder or anything else inside it. I've tried using gksu-nautilus to change the permissions but it doesn't work. When I open the properties window, and select a different level of permission for myself, it instantly switches back to the previous setting.

Any idea of how to fix this?

    what happens if you changed file permission from the command line? – Lie Ryan Jun 6 '11 at 18:20
  • Read my anwser, comment it. I also had problems with nautilus, maybe a bug, or not the right permission. – antivirtel Jun 6 '11 at 18:25

Use commands, from terminal. Ctrl + Alt + T by default, but you can find it in GNOME menu.

So open that terminal, and type:

sudo chmod 775 FILE(S) - for folders, use recursive option: sudo chmod 775 DIR(S) -R

The numbers are from the permissions: 7 means rwx(read, write, execute), 5 r-x(read, execute), 6 rw- (read, write).

The tree number combination is: ogx (owner, group, everyone).

To change group an owner, use:

sudo chown OWNER:GROUP FILE/FORDER -R eg. owner: root, group:users; (R=recursive)

To change group only, use:

sudo chgrp GROUP FILE/FOLDER -R ... same thing...

Please read the manual pages of these programes: man chmod chown chgrp - for more details.


You said "the permissions switch instantly back". What about "the permissions did not get applied"?

If you've a separate /var/www partition formatted FAT or NTFS, you need to reformat your partition as those filesystems do not support Linux file permissions.

Backup your files and re-format the partition as ext4. Next, copy the files back and restore the permissions and ownerships:

sudo chown -R 0:0 /var/www
sudo find /var/www -type f -exec chmod 640 {} \;  # files
sudo find /var/www -type d -exec chmod 750 {} \;  # directories

The 640 and 750 in the last two commands can be changed of course.

  • the problem is precisely because of the file system. Copy the things to a native linux partition ext2,3 or 4 and then check for change in file permission. – Vineet Menon Oct 8 '11 at 5:24
  • Was directed from here: stackoverflow.com/questions/42433649/… This was my exact problem. I have no knowledge about file systems but when you mentioned permissions are not even applying I knew that was it. – Jordan Jun 6 '17 at 17:20

Just change the owner of the folder by opening a terminal and:

sudo chown myUsername:myUsername -R /var/www

Where myUsername is your username
