Impossible to install nextcloud?

Apps & App Center
1

Hi there, I’m trying to install nextcloud app from the app store. Install always works fine, but the join script 50nextcloud never goes through.
At first it stuck because I manually had to create an LDAP-Container “univention/saml-serviceprovider”, as i learned from this post:

Now I’m stuck with this error: “Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[08006] [7] connection to server at “172.17.42.1”, port 5432 failed: FATAL: Passwort-Authentifizierung für Benutzer »nextcloud« fehlgeschlagen”

I can’t spot any help for this error. Which database? Where to create this user?

My gerenal question is: Is it really that hard to install nextcloud, or am I missing some prerequisites? What am I doing wrong? Is there any manual about what steps need to be done to get this to work? Any help appreciated!

Thanks!
Chears,
Roland

Hi Roland, I have the same problem.
After uninstalling and clean Nextcloud, I want to install a fresh Nextcloud.

I got the same 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 “172.17.42.1”, port 5432 failed: Connection refused

The joinscript nextcloud50 did’t run successfully.

I went in the Nextcloud dockler conainer with
univention-app shell nextcloud

apt-get install telnet
telnet 172.17.42.1 5432
Trying 172.17.42.1…
telnet: Unable to connect to remote host: Connection refused

So the docker container can’t access the Univention Postgres DB

Back on the UCS console
netstat -nlp | grep 5432
shows an empty result

The problem is in the file /etc/postgresql/11/main/postgresql.conf
listen_addresses = ‘’

change it to
listen_addresses = ‘*’

After a restart of postgres
service postgresql restart

netstat -nlp | grep 5432
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 1035/postgres
tcp6 0 0 :::5432 :::* LISTEN 1035/postgres
unix 2 [ ACC ] STREAM HÖRT 24707 1035/postgres /var/run/postgresql/.s.PGSQL.5432

The ports are open

Now the joinscript nextcloud50 works as it should

Best regards

Hello Stephan,

thanks a lot for the obvious solution, I lacked the time to investigate the issue, but that sounds good. For now I’m living with an alternate solution (nextcloud) on a different host, not UCS, but I will put the original idea in place and install nextcloud on UCS, so thanks for your post! I wonder why no one bothers tu correct the join-script. I thought the idea of UCS was to keep things quick, neat and easy… with those errors in the join-script it actually is much easier to install nextcloud on any common linux dristribution via cli.

Cheers,
Roland
