I have followed the automatic installation tutorial for ownCloud, from software.opensuse.org,. Needless to say, it didn't go as smooth as apt-get install and enjoy. After installing, enabling SSL with a self-signed certificate and using the absolute default settings I was greeted with a not so nice message below.
|Internal server error message when trying to access mydomain.com/owncloud|
SolutionAfter quite a bit of searching the solution was to add he following lines to the config file /etc/apache2/apache2.conf,.
<Directory /var/www/>Simple edit the file by
Options Indexes FollowSymLinks
Require all granted
sudo nano /etc/apache2/apache2.confand add the mentioned lines to the end of the file.
Save changes with CTRL+O, exit with CTRL+X. Then restart apache2 with
sudo service apache2 restartOr in case you are running Ubuntu 12.04
sudo /etc/init.d/apache2 restartYour error should be fixed and ownCloud ready to be used.
