[Tfug] Two factor authentication

[TR]

Steve,

Yous state sudo <something>,  not all sudo make sense, such as  sudo cd, So
the first question is do all sudo fail?   What does sudo id produce?
As a temporary test I would add rw to others on the device, and try, just
to eliminate the permissions on the /dev/...
