View source for Seamless Software Update

[http://en.wikipedia.org/wiki/Maemo_(operating_system)#SSU SSU] is Nokia's new method for upgrading the tablets. Rather than requiring a [[updating the tablet firmware|reflash]] as with previous updates, SSU updates are pushed over-the-air and installed onto your live system. When Nokia pushes an update over SSU, you will see an update notification and be given the option to install the update—just like with your computer.

== Installing ==

Once a new update is pushed, you will either see a flashing notification in your statusbar, from which you can open Application manager and install the update. If you don't see the notification, then you can simply open Application manager manually, tap "Check for updates", make sure the catalogs are up to date (hit the little rotating circle in the toolbar if it doesn't refresh automatically), and install the update from there. If you still can't see the update, see [[Seamless Software Update#osso-software-version|osso-software-version]].

== initfs and kernel ==

Generally speaking, SSU updates should be relatively pain-free, but there are a few issues to watch out for. If you have an aftermarket kernel or intifs installed (like the rotation support kernel or [[Booting_from_a_flash_card#Install_bootmenu|fanoush's bootmenu]]) and a kernel or initfs upgrade is pushed, they will be overwritten and you'll need to wait for your kernel or the bootmenu to be updated to reinstall them.

== osso-software-version ==

If the update doesn't show up for you at all, you may have accidentally (or intentionally) uninstalled osso-software-version-rx*4, which is required to update. You can get it back by simply running an <code>apt-get install osso-software-version-rx34</code>, for the N800, and an <code>apt-get install osso-software-version-rx44</code>, for the N810. Then updating your repository list in Application manager.

== Unlocking ==

The osso-software-version-rx* meta packages lock the configuration of a device down to the officially
released versions of the OS packages.  This gets in the way when you want to install your own versions
of OS packages.  To get around this, you can install one of the the osso-software-version-rx*-unlocked packages: they depend on the same set of OS packages, but they depend on them with "(<= VERSION)" expressions.  This allows you to install your own versions of OS packages without losing the rest of the SSU machinery.

The osso-software-version-rx*-unlocked packages are available in the same repositories as the SSU itself.

If you want to remove OS packages, the osso-software-version-rx*-unlocked packages do not help; your only way out is to remove the SSU meta package completely and rely on apt-get to install OS updates.
