Since I can’t even connect to localhost:5000 nor ssh with the last beta1 VM, I went back with the 2015-08-06 release.
After modifying hba_conf and postgresql.conf, I can connect to localhost:5000 and ssh the VM.
But I still can’t connect to the database through pgAdmin, which asks for a password when I’m trying to connect to localhost with postgres user and postgres database (despite I set trust option in pg_hba.con, and not md5).
PS : when typing “psql -h localhost -U postgres”, I get :
SSL connection (cipher: DHE-RSA-AES256-GCM-SHA384, bits: 256)
