Error Upgrade PostgreSQL 9.4 to 9.5 in Debian

Good night
I'm trying to Upgrade PostgreSQL to 9.4 9.5 in Debian 8, I am getting
the below error, what could be wrong?

Command that I used to do the pg_upgrade


/usr/lib/postgresql/9.5/bin/pg_upgrade -b /usr/lib/postgresql/9.4/bin/
\-B /usr/lib/postgresql/9.5/bin/ \-d /var/lib/postgresql/9.4/main \-D
/var/lib/postgresql/9.5/main \-o ‘ -c
config_file=/etc/postgresql/9.4/main/postgresql.conf’ \-O ‘ -c
config_file=/etc/postgresql/9.5/main/postgresql.conf
