Upgrade to Ubuntu 11.10 (Oneiric Ocelot)

I upgraded my Ubuntu 11.04 Natty Narwhal to Ubuntu 11.10 beta 2, code name Oneiric Ocelot, on Oct. 12, before official release few days. Here are my own experience:

1. Make sure you know the admin password for PhpMyAdmin, if installed, before you upgrade. I forgot this password and it took me almost half hour to get out the infinite loop :(
2. An hour for download and another hour to install.
3. Remote desktop 'tsclient' was removed. Used 'RDesktop' or 'Remmina' instead. After using Remmina Remote Desktop client, I liked it. It's better than 'tsclient'
4. Somehow the trash icon in launchpad associated with VLC media. Uninstalled VLC resolve this issue.
