Problem with services.nextcloud

Help
1

Hi, I am new here and tried to setup the nextcloud-service on NixOs 19.09. Unfortunately I only got errormessages like this one:

$ uname -a
Linux debian-Nextcloud 4.19.109 #1-NixOS SMP Wed Mar 11 13:15:13 UTC 2020 x86_64 GNU/Linux

I already tested nginx and postgresql successfully and red the manual twice.
There seems to be a problem with occ upgrade.

How can I solve the problem?

Could you post some related configuration that you have used?

Here my configuration:

$ cat /etc/nixos/nextcloud.nix

{ config, pkgs, ... }:
{

  services.nextcloud = {
    enable = true;
    hostName = "www.my-example-domain.tld";
    nginx.enable = true;
    config = {
      dbtype = "pgsql";
      dbuser = "nextcloud";
      dbhost = "/run/postgresql"; # nextcloud will add /.s.PGSQL.5432 by itself
      dbname = "nextcloud";
      dbpassFile = "/etc/nixos/nextcloud-psql-pw";
      adminpassFile = "/etc/nixos/nextcloud-pw";
      adminuser = "Admin";
    };
    # autoUpdateApps = true;
    maxUploadSize = "20G";
  };

  services.postgresql = {
    enable = true;
    ensureDatabases = [ "nextcloud" ];
    ensureUsers = [
     { name = "nextcloud";
       ensurePermissions."DATABASE nextcloud" = "ALL PRIVILEGES";
     }
    ];
  };

  # ensure that postgres is running *before* running the setup
  systemd.services."nextcloud-setup" = {
    requires = ["postgresql.service"];
    after = ["postgresql.service"];
  };

  services.nginx = {
    enable = true;
    virtualHosts = {
      "www.my-example-domain.tld" = {
         forceSSL = true;
         enableACME = true;
         locations."/" = {
           root = "/var/www";
        };
      };
    };
  };

  networking.firewall.allowedTCPPorts = [ 80 443 ];
}

Hm, the error is still cryptic to me…

One thing I’ve noticed is that you set dbpassFile, but you are using Unix authentication. Maybe you need to remove this one.

The other thing I could recommend is, if this is a fresh installation and you do not mind starting over, to clean up files and database. Maybe the installation didn’t finish well, but it created the config.php file and thus the installation is not running anymore (Source).

Hi joko,

I tried so (1. commenting out all the stuff in the NixOs-Configuration file 2. nixos-rebuild switch 3. nix-collect-garbage 4. restart 5. another nixos-rebuild) but the problem still exists. After deleting the nextcloud-database in Postgresql I got the following errormessage:

I hope that helps.

Now I tried with sqllite instead of psql. It doesn’t work too.
Here the error messages:

Have you tried cleaning up the files, too? Everything on /var/lib/nextcloud.

Thanks for the advice (cleaning the nextcloud-folder and drop the nextcloud-psql-database and nixos-rebuild of course).
With ´sqllite´ instead ´pgsql´ set as database it seems to work (no errormessage so far and the loginscreen appears).
But with Postgresql-Db set I get the following errormessage:

With sqlite as db it seems to work but I can’t login.
I tried the adminuser and adminpass used in the configuration but it isn’t accepted. (I tried the password as plaintext and hashed with mkpasswd -m sha-512)

You specified user nextcloud but the error message says user postgres could not log in.
I just run into the same issue with NextCloud in Docker.
Could you figure it out in the meantime?

I don’t know if it’s related, but in my case I had some spaces in my password, which broke the install with two error messages, at the first compilation it was Too many arguments, expected arguments "command". and then Command "upgrade" is not defined. . See this issue service.nextcloud.config.adminpassFile doesn't accept space-separated passwords · Issue #49487 · NixOS/nixpkgs · GitHub. To fix it, remove the password and delete the folder:

rm -rf /var/lib/nextcloud/
