Update the Ocelot
Update Manager
However recent a build you install, be sure to update Ubuntu at the earliest opportunity. It is a credit to the Open Source community that patches and security updates are applied on a continual and ad-hoc basis. While no computer software is ever guaranteed complete security, you can enjoy the benefits of a well-supported distribution.
You have only to launch the Update Manager and click on 'Check Now' to invoke the update process manually.
Also, don't forget the ‘PowerMenu’ (the top-right cog-wheel icon contains an entry for 'Software up to Date' or 'Updates Available.'
One Conf Sync
OneConf is a new feature of the Software Centre. It keeps a list of all your installed applications in sync across multiple computers, so you can have the same working environment wherever you use Ubuntu. To activate it, open the Ubuntu Software Centre and, from the File menu, choose Sync between computers. You will need to create a Software Center Account, but this is no more onerous than UbuntuOne and has the benefit of profiling and storing your software set-up via Canonical's cloud storage.
You'll no longer have to remember which programs to install when you get access to another Ubuntu instance; but you will need Root privileges for it to synchronise.
(Re-) Enable Third-Party Sources
You may find after upgrading that the 11.10 installer has disabled some of your third-party repositories listed in Software Centre.
Where you have added developers PPA's (Personal Package Archives) and other third-party sources, you should check in Software Center that they still have check marks enabling them, otherwise you'll get no more automatic updates from them.
There may be a good reason why Ubuntu has disabled them; check the distribution version and update any older package sources to match Oneiric or 11.10.
You should check the exact archive name and update the sources line for the new version.
You should also then run a
sudo apt-get update
in a terminal to make sure the package list for those sources is refreshed.
Additional Drivers in Ubuntu 11.10
So my wireless card failed to work after the clean install of Ubuntu 11.10 on the net-book. Consulting the forums, I struggled to get the firmware installed; that is, I failed.
Then I stepped back and consid-ered: run the Additional Drivers search first (go to System Settings > Hardware > Additional Drivers)!
This pulled up the appropriate Broadcom drivers without my having to manually tease out the firmware. It was all working again inside 2 minutes.
Note to self - go for the simple, out-of-the-box solutions first, before you go for hard labor.
How or why the installer missed the wireless adapter, I don't claim to understand – importantly it worked from a boot-up using the 11.10 Live CD, ergo, the hardware has to be compatible!
