@ajlowndes It looks like it was a permissions error. YOu should ensure the update is not run using the root user but the project user. Then check that files/folders have the same user Clear your cache and it should be fine. Take time to read the error again - the answer was there. - Permission denied" - Unable to write in the cache directory Hope this helps Matt
