Hi

I run again in a bug with a corrupt suduers file and this time I did not set
up a password for root, so most likely I have to install everything again.

The error is

sudo shutdown -r now
sudo: /etc/sudoers.d/tde-secure-path is mode 0644, should be 0440
>>> /etc/sudoers.d/README: /etc/sudoers.d/tde-secure-path near line 18 <<<
sudo: parse error in /etc/sudoers.d/README near line 18
