OwnCloud Manual Upgrade

I adopted the below methods from upgrading Wordpress manually and tweak the process for manually upgrading OwnCloud:

Backup
Navigate to your OwnCloud location and run the following to backup your OwnCloud.

rsync -a owncloud/ owncloud.backup/

Download Latest OwnCloud 

wget https://download.owncloud.org/community/owncloud-9.1.1.tar.bz2

replace the link with the latest bz2 file.

Extract the Package

bzip2 -d owncloud-9.1.1.tar.bz2
tar xvf owncloud-9.1.1.tar

this creates "owncloud" directory

Copy the Updated Files

rsync -rtv new_path_version/owncloud/ old_path_version/owncloud/

this syncs any file that has been changed from the new location/version to the old location

Navigate to The Site

Load the site and it will ask you to upgrade the database. Don't do it over the UI, do it manually

Database Upgrade Manually

run the following command from the "owncloud" directory

To test the database upgrade:

sudo -u www-data php occ upgrade --dry-run -v

To execute the database upgrade:

sudo -u www-data php occ upgrade -v
