I am completely new to Raspberry Pi and Raspbian. I needed to access a file from root so i followed this guide and in a terminal went

sudo su


I then logged off the root account and then shut down the Pi normally. Now when I try to boot the Pi I get this error message before the screen goes blank.

Now I don't know how to access my files anymore. Does anyone have any idea how to fix this?

Edit I have added the permissions below enter image description here

  • Have you tried opening a virtual terminal ctrl+alt+F2. Assuming that works what are the permissions and ownership of /home/raspbian/.Xauthority you can get that info using the following command ls -la /home/raspbian. Please edit your question and add the above. Oct 2 '15 at 3:34
  • Try without "sudo su", see what it says.

  • @SteveRobillard I have posted the permissions by logging into root and following your instructions. I can't have more than 2 pictures in my question so I had to delete the other one

  • ok, try this: access the virtual terminal again. then cd /home/raspbian/ then touch .Xauthority then change ownership of the new file to root by doing chown root:root .Xauthority you can read more here askubuntu.com/questions/165921/error-on-boot-12-04/…. Oct 2 '15 at 6:05
  • Ok, i've done that while logged in as root

I have solved my problem. Turns out the problem was caused by corrupt .Xauthority files. I fixed this by first logging on as root. I then ran the following command:

rm .Xauth*

This deleted all the .Xauthority files that were causing the pi not to boot. A simple shutdown command and restarting the Pi solved the problem.

shutdown -h now
