2016-06-10 10:08:52 -0700 asked a question PostgreSQL ODBC driver was not found during install of VTN Coordinator

Hi, I tried to install the VTN Coordinator by doing the steps defined in wiki

However while execute the below command.

/usr/local/vtn/sbin/db_setup I have an error * ERROR: PostgreSQL ODBC driver was not found.

But I installed it (with sudo apt-get install odbc-postgresql ), is anyone having this issue ?

I run Ubuntu 14.04 and I work with Beryllium SR2 release
