Go to the folder your ownCloud installation is in and tar it, in case anything goes wrong.
sudo tar -cjvf owncloud.tar.bz2 owncloud/Since it's now owned by root because of the sudo, make it yours now.
sudo chown orangensaft:orangensaft owncloud.tar.bz2Subscribe to the new ownCloud server repository.
sudo vim /etc/apt/sources.listAdd this line at the bottom:
deb http://download.opensuse.org/repositories/isv:ownCloud:community/Debian_6.0/ /Then add the key, update your repositories and install owncloud.
wget http://download.opensuse.org/repositories/isv:ownCloud:community/Debian_6.0/Release.keyIf your manual ownCloud installation was not in /var/www/owncloud, you need to copy the config file to the new directory.
sudo apt-key add - < Release.key
sudo apt-get update && sudo apt-get install owncloud
sudo cp config.php /var/www/owncloud/config/config.phpThis is a step I didn't have to do: Copy your owncloud/data/ folder! This folder stores all your cloud files! Since I have it configured to a different mount (my /storage/), I was able to skip this.
Check your httpd config - in my case it's Apache: /etc/apache2/sites-available/ - and replace the old path with the new /var/www/owncloud/.
After you've done this, restart your httpd (sudo service apache2 restart) and you're done.
You should now be on version 4.5.7. :)
