could it be possible that you have missed to provide most of the required information like the question of log files, how you did the upgrade and similar?

Hi there, thanks for getting back to me. I couldn’t figure out how to get hold of the log files without logging into ownCloud. Can you point me in the right direction with what I need to provide and how I get hold of it please?

The upgrade was done by downloading the file in the link provided, which then took me to the Ubuntu installer. I ran the installer.

I’ve actually tried this upgrade several times without success. I’ve tried installing from the Tarball and I’ve tried running the shell commands listed here: https://download.owncloud.org/download/repositories/stable/owncloud/index.html

With both I always run into error messages of some sort, the only one that seems to work is downloading this: http://download.owncloud.org/download/repositories/production/Ubuntu_18.04/all/
which then launches the Installer.



i think the most important log files are the ones mentioned here:

It seems the documentation has some notes about both which could help you to identify these:


Great, thank you. Have updated the details above. The OC log file just contains ‘1’ though, nothing else…

Permission denied in /var/www/owncloud/lib/private/Config.php on line 251

At a first glance I see the permissions for the ownCloud installations are not set correctly. For Ubuntu you can fix this with

sudo chown -R www-data:www-data /var/www/owncloud

from the shell. Then I’d recommend to run the upgrade again:

cd /var/www/owncloud
sudo -u www-data php occ upgrade

Does this fix your issue?

Ok, this looks more promising but I’ve hit another issue. I had to install some missing PHP modules to get this going (ZIP, cURL and intl) but now I’m getting this:

January 28, 2019 11:10:58 Repair warning: You have incompatible or missing apps enabled that could not be found or updated via the marketplace.
January 28, 2019 11:10:58 Repair warning: Please install or update the following apps manually or disable them with:
occ app:disable logreader
occ app:disable passwordpolicy
January 28, 2019 11:10:58 Repair warning: For manually updating, see https://doc.owncloud.org/server/10.0/go.php?to=admin-marketplace-apps
January 28, 2019 11:10:58 OC\RepairException: Upgrade is not possible

January 28, 2019 11:10:58 Reset log level

I’ve tried running the command ‘occ app:disable logreader’ but I get: “Command ‘occ’ not found”

I’m glad you made it this far. occ ist best called from within the ownCloud installation directory. So change to it with

cd /var/www/owncloud

every time you want to use occ. Then you may disable the mentioned apps with

sudo -u www-data php occ app:disable logreader

and the same for passwordpolicy. Then run the upgrade again.

I’m afraid the logreader is not available any more (does anybody know more about this?), but after the upgrade you can re-install the Password Policy app directly from the Marketplace with

sudo -u www-data php occ market:install password_policy

Thanks so much for all your help guys, I feel like I’m getting closer… but still no cigar.

I did as you advised and this time it seemed to run the upgrade to the end. I then re-installed the password policy and restarted Apache.

But when I go to localhost/owncloud I get: ‘Not Found. The requested URL /owncloud/index.php/login was not found on this server. Apache/2.4.29 (Ubuntu) Server at localhost Port 80’

This looks like an issue with the apache configuration. Does the configuration as cited in the docs
https://doc.owncloud.org/server/10.0/admin_manual/installation/source_installation.html#apache-configuration-label work for you?

Amazing, this worked! Thank you so much, you guys rock!


Hi everyone,

Looks like I am encountering the same issue, after an update yesterday, any accessed document opens into a blank page, from any browsers, the dokuments are still downloadable though.

Trying to follow your recomendation from the link you provided but can’t find the #apache-configuration-label part anymore from that link

Did anything change since then?
