Nextcloud fresh install - Error: Command "upgrade" is not defined.

[afix-space]

Hi,
I'm testing nextcloud it seem there is an issue.
I'm tying to install a fresh nextcloud and with the minimal example of the man : https://nixos.org/manual/nixos/stable/index.html#module-services-nextcloud

I get :

janv. 29 16:56:31 cloud systemd[1]: Starting nextcloud-setup.service...
janv. 29 16:56:31 cloud nextcloud-setup-start[20532]: Nextcloud is not installed - only a limited number of commands are available
janv. 29 16:56:31 cloud nextcloud-setup-start[20532]:
janv. 29 16:56:31 cloud nextcloud-setup-start[20532]: Command "upgrade" is not defined.

nextcloud-setup-start try to update a new install

same result with :
nixpkgs.config.permittedInsecurePackages = [ "nextcloud-19.0.6" ];
or
package = pkgs.nextcloud20;

I may not be calling all the maintainers in case it's a false alarm :-)

I just ran into this too, with nextcloud20 as my package. Running nextcloud-occ list doesn't show an upgrade command.

[IslandUsurper]

I ran the maintenance:install command manually, and now upgrade shows up. Not sure why it didn't install through nix, though.

[afix-space]

Thanks, it works for me too.
It must certainly come from the test.
if [[ ! -e /var/lib/nextcloud/config/config.php ]]; then
I'll check that later.

[Ma27]

Cannot reproduce this on latest master and release-20.09. Can you please give me a minmal VM config that I can use to reproduce?

[afix-space]

Same config works in a test VM.

I'll try to take a closer look next week if it's still relevant.

[DieracDelta]

I am running into this error as well with about the same config as afix-space. Specifically I'm using this configuration without the nginx stuff (e.g. lines 5 to 27 commented out and services.nextcloud.nginx.enable not set) for nextcloud20 on both nixpkgs master and release-20.09. I'll try it in a VM and report back..

[DieracDelta]

It doesn't look like the builds of nextcloud and postgres are cleaned up completely, which is where it looks like this problem is coming from. Specifically, I had built nextcloud and postgres several times while I worked out the configuration settings I wanted. It turns out there were nextcloud and postgres folders in /var/lib that still remained after I uninstalled both apps. Removing those two folders, then reinstalling these programs via nix fixed the error for me.

[beardhatcode]

When I've first set up Nextcloud i encountered the same issues @DieracDelta is describing, but since then everything has run smoothly for me.

[eliasp]

It might sense to verify the installed: true/false result of status after the maintenance:install block, before executing upgrade, e.g. using --output=json and jq -e '.["installed"], where -e causes jq's returncode to represent the boolean value of installed.

The --output=json of nextcloud-occ is unclean. Instead of returning simply JSON, it also returns an informative message on the same FD:

Nextcloud is not installed - only a limited number of commands are available
{"installed":false,"version":"20.0.5.2","versionstring":"20.0.5","edition":""}

Although this should be fixed upstream in the long term (see also nextcloud/server#23596), it needs to be stripped away for now (e.g. using grep -v ...).

[Ma27]

#112013 may prevent corrupted installations in some cases. But I'm still missing a minimal VM setup to reproduce.

[afix-space]

I thought I gave one. I 'm very new with nixos but I would be delighted to learn more. maybe you can give me a link or guide me to do this? or pass the assignees to someone that can reproduce it. thanks

[Ma27]

Well, that's the test VM's config that I already checked. Was there any existing state in /var/lib/nextcloud during your install attempt?

[afix-space]

I don't know I need to reproduce this on the machine in question. i can try

[Ma27]

@eliasp have you checked whether repeated occ:install calls are actually safe? Especially if you want to "work out" your options iteratively.

I don't know I need to reproduce this on the machine in question. i can try

Yeah please do that. You can also answer my question "Was there any existing state in /var/lib/nextcloud during your install attempt?". This is IIRC the main cause for problems like this.

[afix-space]

I don't have access to the machine but I've just started a vps and the same config works with the same steps.
the problem would not have been solved :-) ?
I'm going to look at the merge for the fun

[afix-space]

cool merge :-) I've used adminpass = "abcd1234" on vps may be this is the trick.
And ok I just read other posts.

[afix-space]

@Ma27 do you really need me to reproduce the problem ? it's really very easy and I know you are active in others post who explain the problem.
If you really need that I have a vps whith the bug.

[Ma27]

Well, I'm trying to check if there are any other causes apart from an existing state. Hence my question whether there was any existing state when you encountered the issue.

[afix-space]

I don't know in any case, /var/lib/nextcloud/* seems to be the same between the 2 generations

[alarsyo]

Hit this too:

I'd misconfigured the postgres database (the nextcloud module doesn't setup a nextcloud user and role on the db, which I'm used to for other modules), so the nextcloud-setup service errored out with a database "role doesn't exist" issue. Once I fixed this, I hit this problem, which went away with a good old rm -rf /var/lib/nextcloud.

[Ma27]

To me it seems as if most of the issues here are because the initial install failed and then the app wasn't properly installed, correct?

Rather than letting this stall here even more, I'd write a few more notes in the documentation.

[poly2it]

I'm getting this issue on unstable.

[poly2it]

rm -rf /var/lib/nextcloud "worked" for me.

[axelsimon]

I'm getting it on 24.11:
nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11"

No luck on removing the /var/lib/nextcloud dir either.

[Ma27]

I'll lock this issue now. It is four years old and the module has changed in a lot of ways, so I doubt that any of this is related to the original problem.

If you encounter this: file a clear & concise bug-report that includes nixpkgs rev, logs, nixos config, things you've tried, whether it's a fresh install. There's even an entire section in the manual for things to check!

I can't help anyone if the bugreports consist of two sentences missing 99% of the information I'd need to give a qualified answer.
