Steps to reproduce

1. Start the web based updater from within nextcloud.
2. The update process proceeds without erros and when asked if maintenance mode should be kept active answer yes
3. Start terminal and do as the updater instructs, trigger the migration by running ./occ upgrade

Expected behaviour

I expect the upgrade to finish and me having an upgraded nextcloud installation.

Actual behaviour

The uppgrade process starts and then fails after a while. From what i can see it fails during the migration of data belonging to the news app.

Restarting the upgrade once again, by running ./occ upgrade finishes the upgrade with no further errors. But leaves me wondering what state my installation is in.

Browser log

Browser log

I dont think there are any relevant browser logs to include. The whole failure occurs outside of the browser, and i sadly dont have any console logs left after the uppgrade procedure from the web browser. I might be able to trigger this whole thing again if it is badly needed.

[anoymouserver]

related to #820 (same but other class constant)

[ArmyOfMonkies]

FYI i have a snapshot of the 19.0.4 install from just before the uppgrade to 20.0.0 so i can do the whole ting again, with a bit of manual work.

[dmp1ce]

What do I do to complete the upgrade after a crash like this?

I just ran occ upgrade again and it skipped the news plugin update. I hope that was the right thing to do.

[ArmyOfMonkies]

What do I do to complete the upgrade after a crash like this?

I just ran occ upgrade again and it skipped the news plugin update. I hope that was the right thing to do.

I have no clue on what state the database tables for the news app will be in, or any other tables for that matter. I would recommend to restore from backup or snapshot and await a fix for this before uppgrading to 20.0.

I have not enough understanding of what goes wrong to be able to investigate this myself, but as i have snapshots if anyone tells me what to do i can redo the whole thing, trigger the bug and dump additional information.

[julienfastre]

I could start the container by removing the directory containing the news app.

Then the container started and I could resume upgrade process by using php occ upgrade.

I did not tryed to re-install the news app.

[mcorteel-harel]

The migration worked well with this simple patch:

apps/news/lib/Migration/MigrateConfig.php:49
-         $this->defaults = $application::DEFAULT_SETTINGS;
+         $this->defaults = Application::DEFAULT_SETTINGS;

I'm not sure why the constant would be accessed on the $application instance instead of the Application class anyway...

EDIT: The migration worked, but the news App doesn't work anymore...

[SMillerDev]

That's odd, that class constant didn't work before.

[rubo77]

I had the same issue in a docker-image when upgrading nextcloud from 19.0.4.2 to 20.0.1.1

I fixed it by calling this

docker exec --user www-data nextcloud_app_1 php occ upgrade
docker exec --user www-data nextcloud_app_1 php occ maintenance:mode --off   

[SMillerDev]

Should be fixed in the latest release

[bardo]

This just happened to me while ugrading from 19.0.5 to 20.0.2 on SmartOS/Nginx/PostgreSQL/PHP-FPM.

The occ upgrade command crashed and did not proceed looking for updates for the rest of the apps. A manual run of occ upgrade succeeded.
