Steps to reproduce

1. Upgrade from 8.0.4 to 8.1 using occ command:

apt-get update
aptitude full-upgrade -y
sudo -u www-data php /var/www/owncloud/occ upgrade

sudo -u www-data php /var/www/owncloud/occ app:enable mail
sudo -u www-data php /var/www/owncloud/occ app:enable calendar
sudo -u www-data php /var/www/owncloud/occ app:enable contacts
sudo -u www-data php /var/www/owncloud/occ app:enable documents

1. Now I got WSOD and can't access ownCloud at all so I figured I will delete the contacts app from the system, and so I did.
2. Disable contacts

root@en0ch:/var/www/owncloud# sudo -u www-data php occ app:disable contacts
contacts disabled
root@en0ch:/var/www/owncloud#

Now it works again, but shouldn't be like this.

Expected behavior

ownCloud should upgrade to 8.1 without any issues

Actual Behavior

I get WSOD because some error with the contacts app, and have to delete the contacts app to make it run again.

Very likely related to: #16314

[enoch85]

@RealRancor Maybe, but this is the contacts app. Calendar has no issues anymore, at least for me.

[PVince81]

I think the contacts app wasn't published yet for 8.1, so you probably got the 8.0 version which isn't compatible

[PVince81]

@DeepDiver1975 ?

[PVince81]

@enoch85 the CLI upgrade doesn't auto-download the latest code for third party apps AFAIK.
You have to do enable the app from the web UI to make that happen.

Hmmm, but I think it would make sense to have CLI app enabling also auto-download/update/install the app ?

Contacts 0.4.0.0 works here just fine with oC 8.1

[PVince81]

Ok, then it means it's "./occ app:enable" that doesn't auto-download the latest code of the apps.
I'll confirm this.

[PVince81]

Just tried it locally and I was wrong.
./occ upgrade does try and update an app.

I got the line "Update 3rd-party app: calendar" that would download the latest code.

Now the question is why @enoch85 didn't get such line for the contact apps ?
@enoch85 can you check the "apps/contacts/appinfo/version" file and tell us what version it is ?

[PVince81]

Let me try again with the contacts app. Maybe the latest version wasn't on the app store yet when you tried.

[PVince81]

Steps

1. Check out "v8.0.5" tag from git
2. Setup OC in the web UI
3. Enable contacts app from the "Productivity" section, it should be version 0.3.0.19
4. Check out "v8.1.0" tag from git
5. Run ./occ upgrade in the CLI

GuzzleHttp\Exception\RequestException: cURL error 60: SSL certificate problem: unable to get local issuer certificate

It almost worked for me, the SSL error is due to #17446 and is something with my environment.

Nevertheless, this shows that the upgrade process did attempt to update the code.

@enoch85 can you just try again exactly the same as you did before ? I suspect that the contact apps was shortly published to the correct version.

[enoch85]

@PVince81 Like i wrote in the issue, I deleted the contacts app and downloaded it again from the apps menu. It works now, but just wanted to inform you regarding this bug.

Could this be closed then?

[enoch85]

Confirmed. Contacts app is working. Tried on another server.

Still an issue that the occ command don't update the apps properly and I have to press "start update" again when I enter the domain, but that's already known.
