Use

  TERM=gnome

or

  TERM=gnome-256color

note that the TERM variable does never program a terminal nor terminal emulator
but only describes it.

The same holds true for konsole, that is

  TERM=konsole

or

  TERM=konsole-256color

should do the job. And yes I'm aware that the keyboard completion via readline
might not (fully) work
