Weird keyboard events on Linux

[aloneguid]

I'm having an issue in linux terminal, when subscribing to an event:

some_KeyDown(object? sender, Key k) {
  if(k.KeyCode == KeyCode.D2) {
    do something
  }
}

On windows terminals, pressing number 2 hits the "do something" branch, whereas on Linux the keycode for 2 arrives as KeyCode.AltKey.

What am I doing wrong?

P.S. I'm using latest pre-release nuget (2.0.0-pre.251)
