When I tried to upgrade owncloud 8.04 to 8.1, the owcloud updater app did not work and said I was already at the highest version. However when I run
sudo dpkg -l owncloud*
I get that owncloud 8.1 is installed. Version 8.1 was installed to my /var/www/owncloud directory, however I run owncloud at /var/www/cc.com/owncloud. Here are my installation steps.
Backup owncloud folders: see https://blog.chadchenault.com/2015/07/20/updates-in-owncloud-8-ubuntu-linux/

Turn on Maintenance mode:
sudo -u www-data php /var/www/cc.com/owncloud/occ maintenance:mode –on
Rename current owncloud installation and save it in case you need to restore to it
cd /var/www/cc.com/
mv -v owncloud owncloud.8.04
Move owncloud 8.1 to /var/www/cc.com
cp -vR /var/www/owncloud /var/www/cc.com/
Copy old config.php to new files
cp -v /var/www/cc.com/owncloud.8.04/config/config.php /var/www/cc.com/owncloud/config/

Restart you webserver
service apache2 restart
Run the owncloud upgrade

“The upgrade operation takes a few minutes, depending on the size of your installation. When it is finished you will see a success message, or an error message that will tell where it went wrong.” source https://doc.owncloud.org/server/8.0/admin_manual/maintenance/upgrade.html
Here is the last two lines of output indicating success: “Update successful
Maintenance mode is kept active”
