Why might sudo chmod -R a+w * cause
sudo: /etc/sudoers is mode 0640, should be 0440 sudo:
no valid sudoers sources found, quitting
and how might it be made to work?
Since I was not able to create a sencha touch application I run the following command
sudo chmod -R 777 www/*
it causes changing of sudoers mode to 0777 ..
now am not able to run sudo command ...
Following the wiki's advice, I installed ubuntu-zfs.
