Update to nextcloud 20.0 didn't work fine

zabranah · November 25, 2020, 10:29am

I updated from Nextcloud 19 to version 20 yesterday. That should have basically worked, but unfortunately the configuration was not adopted and I am now asked for an administrator account, data directory, database user, etc. The config.php of version 19 is still available!

Can someone help me there please?

Thank you in advance.

greetings
Helmut

This data should be originaly come from UCS ! I don’t know how to get it !

lebernd · November 27, 2020, 9:58am

Hi @zabranah
you are right.
Did you have a look at /var/log/univention/appcenter.log for what exactly went wrong during the update?

Best, Bernd

zabranah · November 27, 2020, 1:38pm

Hello, Bernd,

sorry but the newest information in the appcenter.log are from 22.11.2020. In the Admin-Diary there is a notice

Admin Diary: APP_UPGRADE_FAILURE Alle Einträge im Kontext d46d880d-d2e8-48e9-b764-f4eee4a92f1d Die Aktualisierung von Nextcloud Hub 19.0.4-0 schlug fehl. Fehler 417 Administrator auf ucs 24.11.20, 20:20

Is that a hint for you?

Thanks for your help.

greetings helmut

Hi Helmut,

not really…

you know what version of the app is running?
did you try to upgrade again?
It would be helpful to know why the app upgrade failed. Or at least at what point…

It depends on the setup - but sometimes new installs are easier to make than repairs…? I would really search the logs for the time the upgrade went wrong. It is from the infos here not clear to me in what state your installation is.

Best, Bernd

zabranah · November 27, 2020, 5:49pm

The server runs under UCS 4.4-6 errata 829. Nextcloud runs as docker-image as Nextcloud Hub 20.0.2-0.

I now searched in other logs but didn’t find “nextcloud” or “docker” in any of them.

As you see in the screenshot in the first message, i can start nextcloud in the browser, but there is not the right configuration.

Helmut

lebernd · November 27, 2020, 7:46pm

can you check the status of the nextcloud join-script on the server?
all the necessary information for the database should be in your config.php
look around for a user nc_admin and the password for this user /var/lib/univention-appcenter/apps/nextcloud/data/integration/admin.secret.

zabranah · November 28, 2020, 1:22pm

Hello, Bernd,

the join-script for docker and nextcloud is documented as OK (“erfolgreich”).

I also tried to login with the data of the config.php and the admin.secret and got the message “The user is invalid because files for this user already exist”. My input was the “nc_admin” and the password from admin.secret.

Thanks a lot.

lebernd · November 28, 2020, 1:38pm

Hm, at this point I would search the nextcloud help for the error. If it happened before and the solutions they’ve found…

Did you change the config.php at some point? Can you get into the docker univention-app shell nextcloud and check why the config.php didn‘t load?
What is the output of univention-app info?

zabranah · November 28, 2020, 5:19pm

No, I never touched the config.php. The last updates were finished without errors.

The output of univention-app info shows UCS: 4.4-6 errata829 Installed: admindiary-backend=1.0 admindiary-frontend=1.0 cups=2.2.1 dhcp-server=12.0 fetchmail=6.3.26 kopano-core=8.7.1.0-1 kopano-webapp=3.5.14.2539-2 kvm=2.8 letsencrypt=1.2.2-8 nextcloud=20.0.2-0 samba4=4.10 uvmm=7.0 z-push-kopano=2.4.5 4.3/dudle=1.2.0-1 Upgradable:.

Yes, i can get into the docker container of nextcloud. Where do you think that i can find why the config.php didn’t load?

Mornsgrans · November 29, 2020, 6:46pm

You can check the updater.log and nextcloud.log in
/var/lib/univention-appcenter/apps/nextcloud/data/nextcloud-data

The config.php can be found inside the docker-container in the folder var/www/html/config/

zabranah · December 7, 2020, 1:19pm

Sorry, it took a little longer!

In the LOG files I couldn’t find any entries from the corresponding date. Have now tried to install VIM in order to edit the config.php manually and got an error message that he could not access the relevant files. Then I put a PING on 8.8.8.8, which also failed. Could it be, as I suspect, that the data transfer somehow failed as a result? What can I do to fix this error?

lebernd · December 7, 2020, 8:26pm

I would then inspect the docker network with:

docker network

Usage:  docker network COMMAND

Manage networks

Commands:
  connect     Connect a container to a network
  create      Create a network
  disconnect  Disconnect a container from a network
  inspect     Display detailed information on one or more networks
  ls          List networks
  prune       Remove all unused networks
  rm          Remove one or more networks

Run 'docker network COMMAND --help' for more information on a command.

starting with: 
docker network ls

If you can’t get anywhere from inside the container, then nextcloud also can’t connect to the database on the host.
You can see the config.php from /var/lib/univention-appcenter/apps/nextcloud/data/integration/config/config.php on the host. Be careful with the file-rights when you need to edit it. It should belong to www-data:www-data

Best, Bernd

I uninstalled Nextcloud again and reinstalled it from the command line. You can then see all error messages on the screen:

Somehow the installation stumbles over existing data of a user. I assume that this then results in the incorrect installation?

I think that with these messages the error is more obvious than with the previous imprecise information on my part. I could have thought of it before.

On the Nextcloud login page I see the empty mask inserted in the first post. As I get the login page in the browser, I think there should be a network connection. Ping to 8.8.8.8 can’t be done because the command is not found.

Thanks and best wishes
Helmut

lebernd · December 10, 2020, 1:44pm

Just as I’ve said - you will find solutions in the nextcloud-help forum. At least I think so as a short search pointed to docker versions that had similar problems.

I would try to delete the folders under /var/lib/univention-appcenter/apps/nextcloud after a deinstall and try again.

Maybe you have to delete the database (postgresql) too?

If you already have data - of course save the files and db.

Best, Bernd

zabranah · December 13, 2020, 7:26pm

Hello, Bernd, I have now backed up all the data, deleted the entire Nextcloud installation including the Docker image, UCS variables, the specified folders and the database entries. The reinstallation has now been completed, but the join script is not executed properly (not even after restarting the server).

These are the corresponding entries in the LOG file:

Unfortunately, that doesn’t say too much to me. Do you have a tip for me?

Thanks Helmut

lebernd · December 13, 2020, 7:49pm

Did you configure SAML at some point for nextcloud?

I’m not sure if this is just the standard by now, (my installations are much older and I had to configure it by hand)

Are you working with SAML for other apps?

curl failed with error 51

seams to be a certificate validation error. So maybe there is a cert from the old installation?

Best, Bernd

zabranah · December 14, 2020, 8:29am

No I’m not working with SAML in any app. And I don’t think that I’ve configured SAML during the installation.

Greetings Helmut
