Updating ownCloud with the Updater App
======================================
Updating and upgrading your ownCloud installation are two different tasks.
Updating means updating to the next point release, which is indicated
by third digit of the version number. For example, 4.5.1, 5.0.17, 6.0.4 and
7.0.1 are point releases. (Look at the bottom of your Admin page to see your
version number.)
Major releases are indicated by the first and second digits. So 4.5.0, 5.0.0,
6.0.0, and 7.0.0 are major releases. The Updater app is not for upgrades;
please see :doc:`upgrade` for instructions on upgrading to a major release.
.. note:: If you installed ownCloud from your Linux distribution repositories
using your package manager, then it is best to update/upgrade ownCloud using
your package manager and staying in sync with your distro updates, rather
than using the Updater app or upgrading manually. You should still
maintain regular backups (see :doc:`backup`), and make a backup before every
update/upgrade.
The Updater app automates many of the steps of updating an ownCloud installation
to the next point release. The Updater app should be enabled in your ownCloud
instance by default, which you can easily confirm by looking on your Apps page.
The Updater app performs these operations:
* Creates a ``backup`` directory under your ownCloud data directory
* Download and extracts updated package content into the
``backup/packageVersion`` directory
* Makes a copy of your current ownCloud instance, except for your data
directory, to ``backup/currentVersion-randomstring``
* Moves all directories except ``data``, ``config`` and ``themes`` from the
current instance to ``backup/tmp``
* Moves all directories from ``backup/packageVersion`` to the current version
* Copies your old ``config.php`` to the new ``config/`` directory
Using the Updater app to upgrade your ownCloud installation is just a few
steps:
1. You should see a notification at the top of any ownCloud page when there is
a new update available:
.. figure:: ../images/updater-1.png
2. Even though the Update app backs up important directories, you should
always have your own current backups (See :doc:`backup` for details.)
3. Verify that the HTTP user on your system can write to your whole ownCloud
directory; on a stock Linux installation this is the ``www-data`` or
``apache`` user on systems that are running the Apache HTTP server. You can
find your HTTP user in your HTTP server configuration files. Or you can
create a PHP page to find it for you. To do this, create a plain text file
with this single line in it:
``<?php echo exec('whoami'); ?>``
Name it ``whoami.php`` and place it in your ``/srv/var/www/html directory``,
and then open it in a Web browser, for example
``http://servername/whoami.php``. You should see a single line in your
browser page with the HTTP user name.
4. Navigate to your 'Admin' page and click the 'Update Center' button under
Updater:
.. figure:: ../images/updater-2.png
5. This takes you to the Updater control panel.

6. Click Update, and carefully read the messages. If there are any problems it
will tell you, otherwise you will see a message about checking your
installation, making a backup, and moving files:
.. figure:: ../images/updater-4.png
8. Click Proceed, and then it downloads the updates, which may take a few
minutes:
.. figure:: ../images/updater-5.png
7. The Update app wants you to be very sure you want to update, and so you must
click one more button, the Start Update button:
.. figure:: ../images/updater-6.png
8. It works for a few minutes, and when it is finished displays a success
message, which disappears after a short time.

Refresh your Admin page to verify your new version number.
If the Update app fails, then you must update manually. See :doc:`upgrade` to
learn how to upgrade manually.
