How to Fix chown Operation Not Permitted

In this tutorial, you'll learn about How to Fix chown Operation Not Permitted. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

The Problem

You run chown to change file ownership and get:

chown: changing ownership of 'file.txt': Operation not permitted

Or:

chown: cannot access 'file.txt': Permission denied

On Linux, only the root user can change the owner of a file. Regular users cannot transfer ownership even if they own the file.

Quick Fix

Step 1: Use sudo

sudo chown user:group file.txt

Enter your password when prompted.

Step 2: Verify ownership

ls -la file.txt

Expected output:

-rw-r--r-- 1 user group 1024 Mar 15 10:30 file.txt

Step 3: Change group only (user can do this)

If you own the file, you can change the group to any group you are a member of:

chown :mygroup file.txt

Or use chgrp:

chgrp mygroup file.txt

Step 4: Recursive ownership change

For directories, use the -R flag:

sudo chown -R user:group /path/to/directory

Alternative Solutions

If you do not have sudo access, request ownership via an admin:

# Admin command
sudo chown your-username file.txt

On some systems, chown is restricted by the CAP_CHOWN capability. Check with getcap:

getcap /usr/bin/chown

Prevention

• Plan file ownership before creating shared directories.
• Use group ownership for collaborative projects.
• Run application services under dedicated users, not root.
• Use ACLs (setfacl) for fine-grained permissions without changing ownership.
