Problem upgrading Ubuntu 16.04 to 18.04

I have updated my Ubuntu version from 16.04 to 18.04

I then changed ‘deb /’ to ‘deb /’ in sources.list and did apt update.

‘<?php phpinfo(); ?>’ shows /etc/php/7.1/apache2

When I got to my owncloud URL I get

Internal Server Error

The server encountered an internal error and was unable to complete your request.

Please contact the server administrator if this error reappears multiple times and include the technical details below in your report.

More details can be found in the server log.

Technical details

Remote Address:
Request ID: TJSfs0K0LkHI1MP6lzpB

But cant find anything in the Apache logs.

Any ideas?

Actual behaviour

Server configuration

Operating system:
Ubuntu 18.4

Web server:

MariaDB 10.1

PHP version:

ownCloud version: (see ownCloud admin page)
Can’t access admin page

Updated from an older ownCloud or fresh install:
from old ver

Where did you install ownCloud from:
deb /

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
paste the results into and puth the link here.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.


If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/…

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/…

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Client configuration


Operating system:


Web server error log

Insert your webserver log here

ownCloud log (data/owncloud.log)

Insert your ownCloud log here

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log
b) The network log 
c) ...

Have a look in your ownCloud log, it is in your data directory and search for the request ID (TJSfs0K0LkHI1MP6lzpB) in there.

Ubuntu 18.04 brings a newer version of PHP than 16.04, so you need to make sure that you have all the required PHP modules installed.

Please don’t use the repositories for updating, this is not doing what you think it does and will actually bring you to an unsupported state.

The repo is for initial installation only, the documentation recommends to disable package updates afterwards.

OK, thanks,got it working. Re the repositores what is it for? How should I keep things up to date (can I just remove it).

As a start I would recommend to read the update manual in our documentation.
And also always read the release notes.
