Problem pg_receivexlog compatible: FAILED (PostgreSQL version: 10.5, pg_receivexlog version: None)

Added PATH to /etc/barman.conf
path_prefix = /usr/lib/postgresql/10/bin

Nothing has changed, what is missing? I didn't find anything suitable in the documentation and in Google.
They write, see pg_receivexlog_path: /usr/bin/pg_receivexlog , so the 10th version of the 1C assembly does not put anything there in principle.

As far as I know pg_receivexlog has become pg_receivewal or am I wrong?
