Unable to edit/delete files through KUDU site (409 conflict: could not write to local resource)

Azure | Unable to edit/delete files through KUDU site(409 conflict: could not write to local resource)

Scenarios

Edit Error

When you open any file in KUDU and try to save after updating, you may get this error.

DELETE Error

 When you try to delete the same file, you may get below error.

These errors are confusing. For example when you try to delete any file and get an exception, “404 Not found” but actually file is available in Folder and visible

Solution

This issue is pertaining to Files permission. You can check the permission of any file using below command,

attrib FileName

e.g.

attrib index.html

When we run this command, we will get details of all permission applied on that file,

We can clearly see that this file has been marked as “Read Only” and can’t be modified or deleted.

               

Once we remove this read-only permission using below command then the user will be able to edit/delete the file.

attrib -r index.html

          you can run attrib -r *.* to do them all at once.

Similarly, there might be some other permissions which can play an important role here.

Attrib Displays, sets, or removes the read-only, archive, system, and hidden attributes assigned to files or directories. Used without parameters, attrib displays attributes of all files in the current directory. Syntax attrib [{+r|-r}] [{+a|-a}] [{+s|-s}] [{+h|-h}] [[Drive:][Path] FileName] [/s[/d]] Top of page Parameters +r   : Sets the read-only file attribute. -r : Clears the read-only file attribute. +a : Sets the archive file attribute. -a : Clears the archive file attribute. +s : Sets the system file attribute. -s : Clears the system file attribute. +h : Sets the hidden file attribute. -h : Clears the hidden file attribute.

Please refer below URL for the complete list of Attrib command.
