Error while trying to create admin user: Failed to connect to the database

[ghost]

I left the passwords to be generated for me (ie blank), all defaults in group_vars/all.yml and now having the following error:

fatal: [localhost]: FAILED! => changed=true
  cmd: |-

Looks like this might be related to #15 which was resolved?

could you execute

docker exec --user www-data nextcloud php occ  maintenance:install  --database pgsql --database-host nextcloud-db --database-name nextcloud  --database-table-prefix oc_ --database-user nextcloud --database-pass somepassword  --admin-user some-user --admin-pass someotherpassword --data-dir /var/nc-data

on the commandline?

is somepassword the password or does it contain some "funny" characters misinterpreted by the commandline?

Still produces the same error message. 😞

Both passwords generated by the play consist of upper, lowercase and numbers. No special characters are present.

This same issue occured for someone else in #22

Could you give me some information about your system? os version, hoster?
