PostgreSQLpgagent "Running at: is not runing"

I have a problem to run pgAgent job for PostgreSQL 9.6 under ubuntu 16.04. The job is never executed. I already configured .pgpass and added: localhost:5432:*:postgres:mypass Also modified the permission for .pgpass: $ touch ~/.pgpass $ chmod 0600 ~/.pgpass After that I run pgAgent with no problem: $pgagent hostaddr=127.0.0.1 dbname=mydb user=postgres When I check the process for pgAgent I would get this result: user@gis-srv:~$ ps aux | grep pgagent user 153179 0.0 0.0 113844 9392 pts/26 S 17:15 0:00 pgagent hostaddr=127.0.0.1 dbname=postgres user=postgres user 153220 0.0 0.0 113844 9360 pts/26 S 17:16 0:00 pgagent hostaddr=127.0.0.1 dbname=mydb user=postgres user 153227 0.0 0.0 12944 936 pts/26 S+ 17:16 0:00 grep --color=auto pgagent Here is my job setting:

My propblen that the job is never executed and there is no error in the errors log for PostgreSQL. Please help me to find out why jobs never run. I am receving the following errors: from postgres.log: 2017-11-03 16:01:32.269 EDT postgres@postgres LOG: could not receive data from client: Connection reset by peer from pgagent.log: (attempt 9): fe_sendauth: no password supplied Fri Nov 3 16:01:32 2017 : WARNING: Couldn't create the primary connection (attempt 10): fe_sendauth: no password supplied Fri Nov 3 16:01:32 2017 : ERROR: Stopping pgAgent: Couldn't establish the primary connection with the database server. Also I modified the permission .pgpass to allow everyone to access it. (Just for testing)
