I am trying to upload image through admin page, but it keeps saying: 

[Errno 13] Permission denied: '/path/to/my/site/media/userfolder/2014/05/26'

the folders userfolder/2014/05/26 are created dynamically while uploading.

In Traceback, i found that the error is occuring during this command:

In /usr/lib64/python2.6/os.py Line 157. while calling 

mkdir(name, mode)

meaning, it cannot create any folder as it doesnot have the permission to do this

I have OpenSuse as OS in Server. In httpd.conf, i have this: 

<Directory /path/to/my/site/media>
   Order allow,deny
   Allow from all
</Directory>

Do I have to chmod or chown something?

  • Make sure the directory `/path/to/my/site/media` is writable by web server process. – falsetru May 26 '14 at 13:04

    `ps aux | grep apache` will show you what user own the process. – falsetru May 26 '14 at 13:07
  • @falsetru this shows me ``root``. so this is my django code, right? – doniyor May 26 '14 at 13:07
  • What about `ps aux | grep httpd | grep -v grep` or `ps aux | grep apache | grep -v grep` ? – falsetru May 26 '14 at 13:10
  • @falsetru 2nd command doesnt show anything, 1st one shows many processes the first one is of root, the rest is of httpd. – doniyor May 26 '14 at 13:12
  • You should change ownership of the directory `/path/to/my/site/media` or change permission so that `httpd` user can write there. – falsetru May 26 '14 at 13:13

    `chown -R httpd:httpd /path/to/my/site/media` (the second `httpd` is group name. You need to change it if the group of the `httpd` is different from `httpd`) – falsetru May 26 '14 at 13:16

You need to change the directory permission so that web server process can change the directory.

  • To change ownership of the directory, use chown:

    chown -R user-id:group-id /path/to/the/directory

  • To see which user own the web server process (change httpd accordingly):

    ps aux | grep httpd | grep -v grep

    OR

    ps -efl | grep httpd | grep -v grep

  • I'm using gunicorn. I get same error message. I want to give gunicorn read/write access to a folder under /home/portfolio. How do I go about it? – KhoPhi Jan 30 '15 at 22:45
  • @Rexford, You'd better post a separated question with `gevent` tag. – falsetru Jan 31 '15 at 02:33
  • @falsetru I solved the issue by changing the owner of main folders and it's subdirectory/files to www-data. I am using flask+apache for backend server. Thanks for your guidance. – Ajay Jun 01 '17 at 15:27

This may also happen if you have a slash before the folder name:

path = '/folder1/folder2'

OSError: [Errno 13] Permission denied: '/folder1'

comes up with an error but this one works fine:

path = 'folder1/folder2'

    It is worth explaining _why_ this happens. A `/` before the folder name in Unix indicates that the folder should exist in the root directory, which also houses all the major sensitive system folders e.g. `/usr/`, `/bin/`, etc. (try it, do `cd /` and see where you land up). Ordinary processes are not permitted to modify the root directory. Omitting a leading `/` defaults the folder to the current working directory, which is perfectly safe and which Unix will do for you. – Akshat Mahajan Aug 23 '16 at 17:59
  • @mjp When i tried to remove the first slash from 'folder1/' it indeed worked and the error was gone, however i have no idea were that folder is now? So where is it? How do i access it? thanks – masky007 Nov 01 '18 at 02:42
  • I created a folder called folder1 in you current directory – yasin mohammed Feb 11 '20 at 14:14

Probably you are facing problem when a download request is made by the maybe_download function call in base.py file.

There is a conflict in the permissions of the temporary files and I myself couldn't work out a way to change the permissions, but was able to work around the problem.

Do the following...

  • Download the four .gz files of the MNIST data set from the link ( http://yann.lecun.com/exdb/mnist/ )
  • Then make a folder names MNIST_data (or your choice in your working directory/ site packages folder in the tensorflow\examples folder).
  • Directly copy paste the files into the folder.
  • Copy the address of the folder (it probably will be ( C:\Python\Python35\Lib\site-packages\tensorflow\examples\tutorials\mnist\MNIST_data ))
  • Change the "\" to "/" as "\" is used for escape characters, to access the folder locations.
  • Lastly, if you are following the tutorials, your call function would be ( mnist = input_data.read_data_sets("MNIST_data/", one_hot=True) ) ; change the "MNIST_data/" parameter to your folder location. As in my case would be ( mnist = input_data.read_data_sets("C:/Python/Python35/Lib/site-packages/tensorflow/examples/tutorials/mnist/MNIST_data", one_hot=True) )

Then it's all done. Hope it works for you.

Another option is to ensure the file is not open anywhere else on your machine.

  • This only applies to Windows. It looks like this question is directed at Linux. There these restrictions do not exist – Dick Kniep Jan 03 '19 at 13:52

Simply try:

sudo cp /source /destination

supplementing @falsetru's answer : run id in the terminal to get your user_id and group_id

Go the directory/partition where you are facing the challenge. Open terminal, type id then press enter. This will show you your user_id and group_id

then type

chown -R user-id:group-id .

Replace user-id and group-id

. at the end indicates current partition / repository

// chown -R 1001:1001 . (that was my case)

Just close the file in case it is opened in the background. The error disappears by itself
