Hello
I’m trying to install Nextcloud on Ubuntu with a PostgreSQL backend. Unfortunately occ is acting up.
Prior to installation I’ve done the following preparations:
$ sudo -u postgres psql -d template1
template1=# CREATE USER ncadmin WITH PASSWORD 'password' CREATEDB;
template1=# CREATE DATABASE nextcloud_db OWNER ncadmin TEMPLATE template0 ENCODING 'UTF8';
template1=# GRANT CREATE ON SCHEMA public TO ncadmin;
template1=# \q
I’m doing a manual install so I’ve downloaded a tarball and uncompressed it in /var/www/nextcloud:
$ sudo -u www-data php occ maintenance:install --database ‘pgsql’ --database-host ‘/var/run/postgresql’ --database-name ‘nextcloud_db’ --database-user ‘ncadmin’ --database-pass='password' --admin-user='admin' --admin-pass='password' --data-dir ‘/mnt/ncdata/’
This provides the following error:
An unhandled exception has been thrown:
Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[08006] [7] connection to server at "localhost" (127.0.0.1), port 5432 failed: fe_sendauth: no password supplied in /var/www/nextcloud/lib/private/DB/Connection.php:139

I’ve tried both with and without the ‘--database-host’ option inspired by this. Made no difference.
Obviously I’ve changed all passwords before posting 
What’s the problem? I wouldn’t mind just using peer authentication in PostgreSQL but I couldn’t make occ accept that so I ended up setting a password to the ncadmin user in PostgreSQL.
I literally have no clue so I would appreciate any hints.
Thanks
