[Guide] Installing Ubuntu 11.10 Oneiric in VirtualBox 4.1.4

To upgrade from Ubuntu 11.04 on a desktop system, press Alt+F2 and type in “update-manager -d” (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release ’11.10′ is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 11.04 on a server system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.

4. Revised DVD content. With 11.10 Beta 1, we’re introducing a revised smaller DVD based on community feedback over the last few cycles. This new DVD has a more manageable size of 1.5G. The new DVD image is an extension of our current CD image to include all the language packs and some other useful applications, such as Inkscape, GIMP, Pitivi, and a more complete LibreOffice suite. All the packages that used to be on the DVD are still available from the archive.
5. Interface updates
A new release of compiz and Unity has been included with this milestone. Highlights of this release are:
A new Alt+Tab switcher.
“Places” were renamed to “Lenses”, now integrating multiple sources and advanced filtering like ratings, range, categories. A new music lens linked to Banshee is also installed by default. The restructuring for getting some new features has been done. Known bugs and regressions are documented below.
Better performance of launchers and panel, ported to GTK 3 and GTK 3-based indicator stack.
