Have you tried so set max_wal_senders to a higher value? iirc the
default value for postgresql10 is max_wal_senders = 10

also worth checking is your servers barman conf file
(/etc/barman.d/xxx.conf) which has a line at the end pointing to the
postgres binaries path to use.
What means that you have to have postgresql-client package version 10 on
your barman server and have to change your config pointing to the new path.
kind regards
