"For the average business or personal computer user, Ubuntu is one of the easy to use free Linux operating systems which makes for a much more stable and pleasant user experience than the infamous Microsoft Windows. It thus comes as a surprise, to have a headache with an Ubuntu upgrade.
"Having just spent days restoring data due to the impossibility of migrating back the entire Operating System from Ubuntu 9.10 to 9.04, seemingly because the Master Boot Record contains changes in this latest version as well as the home folder encryption system maybe forwards but not easily backwards compatible, I thought it best to write about the experience and save others the headache.
"Firstly, there is absolutely nothing wrong with 9.04 (Jaunty) Ubuntu alternate - with the latest updates of Kernel 2.6.28-16 Generic running on a new ASUS UL30A laptop. Everything works - including Wireless WLAN, Bluetooth, OpenVPN, LAN, although Skype video requires a fix due to running upside down, this is the fault of both Skype and the camera being mounted upside down in some laptops, and nothing to do with Ubuntu."
