# Upgrade ownCloud From Packages

## 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:

Warning

Make sure that you don’t skip a major release when upgrading via repositories. For example you can’t upgrade from 8.1.x to 9.0.x directly as you would skip the 8.2.x major release. See Upgrading Across Skipped Releases for more information.

- Disable all third-party apps.
- Make a fresh backup.
- Upgrade your ownCloud packages.
- Run occ upgrade (Optionally disable the Migration Test which might take a long time on large installations).
- Apply strong permissions to your ownCloud directories.
- Take your ownCloud server out of maintenance mode.
- Re-enable third-party apps.

Warning

When upgrading from oC 9.0 to 9.1 with existing Calendars or Addressbooks please have a look at the 9.0 release notes for important information about the needed migration steps during that upgrade.

## 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

Optionally disable the Migration Test which might take a long time on large installations.

See Using the occ Command to learn more.

## Setting Strong Directory Permissions

After upgrading, verify that your ownCloud directory permissions are set according to Setting Strong Directory Permissions.

## Upgrading Across Skipped Releases

It is best to update your ownCloud installation with every new point release (e.g. 8.1.10), and to never skip any major release (e.g. don’t skip 8.2.x between 8.1.x and 9.0.x). If you have skipped any major release you can bring your ownCloud current with these steps:

1. Add the repository of your current version (e.g. 8.1.x)
2. Upgrade your current version to the latest point release (e.g. 8.1.10) via your package manager
3. Run the `occ upgrade` routine (see Upgrade Quickstart above)
4. Add the repository of the next major release (e.g. 8.2.x)
5. Upgrade your current version to the next major release (e.g. 8.2.8) via your package manager
6. Run the `occ upgrade` routine (see Upgrade Quickstart above)
7. Repeat from step 4 until you reach the last available major release (e.g. 9.1.x)

You’ll find repositories of previous ownCloud major releases in the ownCloud Server Changelog.
