    I bet you don't have xbase-clients installed on the remote system.

    No, they aren't.

    You shouldn't do it like that. This is a common mistake, but it breaks
    the scp protocol. Guard the debug message such that it only gets
    displayed for interactive shells, something like this:

      case $- in
        *i*)
          echo 'executing /etc/bash.bashrc'
          # other interactive stuff goes here, if you want
          ;;
      esac

    You installed them both, probably. ;)

    ssh2 wasn't properly maintained for a long time, is non-free, and has
    been removed from Debian. 'dpkg --purge ssh2' is probably what you want.

    Cheers,
