Upgrade ownCloud From Packages¶
Changes in ownCloud 8.2¶
- The Linux package repositories have changed, and you must configure your system to use these new repositories to install or upgrade ownCloud 8.2+. The new repositories are at our Open Build Service.
- Apache configuration files are in a separate package,
owncloud-config-apache
.
Upgrade Notes¶
If you are using a custom theme, the upgrade changes it back to the default
theme. After the upgrade is completed and you have verified that everything
works correctly, change back to your custom theme by entering the path
to your theme with 'theme' => '',
in your config.php
file. If your
custom theme causes any issues, comment out 'theme' => '',
to restore the
default theme.
owncloud/core/skeleton/
is overwritten on upgrades. If you wish to provide
a set of default files, place them in a different directory such as
owncloud/config/skeleton
. Then enter this path in config.php
with the
'skeletondirectory' => '/path/to/folder',
directive.
Upgrade Quickstart¶
The best method for keeping ownCloud current on Linux servers is by configuring your system to use ownCloud’s Open Build Service repository. Then stay current by using your Linux package manager to install fresh ownCloud packages. After installing upgraded packages you must run a few more steps to complete the upgrade. These are the basic steps to upgrading ownCloud:
- Disable all third-party apps.
- Make a fresh backup.
- Upgrade your ownCloud packages.
- Run occ upgrade (optionally disabling the migration test).
- Apply strong permissions to your ownCloud directories.
- Take your ownCloud server out of maintenance mode.
- Re-enable third-party apps.
Upgrade Tips¶
Upgrading ownCloud from our Open Build Service repository is just like any normal Linux upgrade. For example, on Debian or Ubuntu Linux this is the standard system upgrade command:
apt-get update && apt-get upgrade
Or you can upgrade just ownCloud with this command:
apt-get update && apt-get install owncloud
On Fedora, CentOS, and Red Hat Linux use yum
to see all available updates:
yum check-update
You can apply all available updates with this command:
yum update
Or update only ownCloud:
yum update owncloud
Your Linux package manager only downloads the current ownCloud packages. Then your ownCloud server is immediately put into maintenance mode. You may not see this until you refresh your ownCloud page.
Then use occ
to complete the upgrade. You must run occ
as your HTTP
user. This example is for Debian/Ubuntu:
sudo -u www-data php occ upgrade
This example is for CentOS/RHEL/Fedora:
sudo -u apache php occ upgrade
Migration Test¶
Before completing the upgrade, ownCloud first runs a simulation by copying all
database tables to new tables, and then performs the upgrade on them, to ensure
that the upgrade will complete correctly. The copied tables are deleted after
the upgrade. This takes twice as much time, which on large installations can be
many hours, so you can omit this step with the --skip-migration-test
option, like this example on CentOS:
sudo -u apache php occ upgrade --skip-migration-test
Setting Strong Directory Permissions¶
After upgrading, verify that your ownCloud directory permissions are set according to Setting Strong Directory Permissions.
If the upgrade fails, then you must try a manual upgrade.
