Server configuration

Operating system: Ubuntu 16.04

Web server: Apache 2.4

Database: MySQL

PHP version: php7

Solution:

To solve the problem I performed a reinstall:

sudo apt-get install --reinstall owncloud-files

After the reinstall, I compared the previous and reinstalled 9.0 installation line by line. The difference is that the previous installation had this setting:

diff -wBdr /tmp/owncloud/.htaccess /var/www/owncloud/.htaccess
92,105d91
< #### DO NOT CHANGE ANYTHING ABOVE THIS LINE ####
< 
< ErrorDocument 403 /owncloud/core/templates/403.php
< ErrorDocument 404 /owncloud/core/templates/404.php
< <IfModule mod_rewrite.c>
<   RewriteRule . index.php [PT,E=PATH_INFO:$1]
<   RewriteBase /owncloud
<   <IfModule mod_env.c>
<     SetEnv front_controller_active true
<     <IfModule mod_dir.c>
<       DirectorySlash off
<     </IfModule>
<   </IfModule>
< </IfModule>

This change is not present in the reinstalled oC 9.0, which fixes the issue.

Do you still have the problem?

If so, make sure your config overwrite.cli.url is set to the correct value.

[emmenlau]

Ahh, does the problem has to do with overwrite.cli.url? I never changed this parameter until a few days ago, was there maybe a default or did I set this during install? It was indeed wrong! Thanks for clarification!

@emmenlau It will be set to the URL which is used during the initial setup. If you're changing the URL (like from http://www.example.com/owncloud to http://www.example.com) the mentioned config option needs to be updated.

To workaround such issues oC 9.0.3 won't automatically enable the index.php-less URLs and the admin needs to correctly configure this initially.

[emmenlau]

I understand! I think I set this wrongly on the first install, and never changed it later. It was not a problem on a number of upgrades, and now suddenly turned into a blocker. Thanks for the hint!
