Hi. Friends don't help friends to do bad things :)

Debian's default shell is 'dash'. Its manual, readable using 'man dash',
says

    Aliases provide a convenient way for naive users to create shorthands
    for commands without having to learn how to create functions with
    arguments.  They can also be used to create lexically obscure code.
    This use is discouraged

To achieve your goal, do this instead.

In .bash_profile, replace the line
  alias k='minikube kubectl --'

with these two lines:
  k() { minikube kubectl "$@" ; }
  export k
