I'm trying to edit the terminal on my Pi and whenever I edit my terminal with the command nano /boot/config.txt this comes up:

nano /boot/config.txt unwritable 

Whenever I try to exit and try to save I get an error message

[Error writing /boot/config.txt: Permission denied]

When issuing your command, if permissions are denied, the easiest way to fix that is to run the command with root privileges.

Like this:

sudo nano /boot/config.txt

sudo basically let's the command after it do whatever it wants (like in your case, let nano write to /boot/config.txt), so be careful.


You need root permission to edit system files.

This can be done with sudo nano but it is much better to use sudoedit

sudoedit /boot/config.txt
