I unistall the 9.6 postgresql version from the Synaptic application, but the problem persists (postgresql 9.6 no longer appears in synaptic's installed software list) īut by executing the command that follows we see that the version postgresql 9.6 was not completely dpkg -l | grep postgresql Is the server running on host 'localhost' (::1) and accepting TCP/IP connections on port 5432? Failed to connect to the database: could not connect to server: Connection refused When I run the comand msfconsole in a terminal, although metasploit connects to the msf database on port 5432, the following error message msfconsole Postgresql 10 listening on port 5433 instead of 5432. So I had two versions of postgresql (10 & 9.6) installed in my debian machine.

When I updated postgresql from the Synaptic application, it is the postgresql 10 version that was installed. Thanks to Code Friendly, & I want to share how I solved my problem.
