may i ask how much experience with cp2k altogether you have?

the input reference clearly states that those are alternates,
i.e. they are all different names for the same thing. it should
actually be self-evident from the theory.

perhaps you should start with something less ambitious to first
master the code altogether and get a better understanding of the
theory and _then_ try something more complicated. also if you
think about metallic systems, you should keep in mind that
to the best of my knowledge, cp2k currently neither supports
fractional occupations nor k-points.

please provide an input that reproduces the error.
an error report that cannot be reproduced is not helping much.

you can print volume and stress via print keys.
