Hi Tim, Thank you so much for your response. I did as you suggested and it's now installed perfectly! Many thanks, Sophie

Hi, I am having a similar problem, however the solution suggested above doesn't appear to work for me. I believe this is due to a fault in my sudoer file, but I'm not computer expert! When typing 'sudo echo hello' into terminal I receive the following message: sudo: /etc/sudoers is owned by uid 501, should be 0 sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin -bash-3.2$ Please can you help me?!
