How to Upgrade to Ubuntu 10.10 Release Candidate?
If you ask me about how safe it is to use a release candidate, well, I have been using Ubuntu 10.10 from its third Alpha and so far not even a single crash. But it's heavily depended on your hardware and more importantly, Ubuntu 10.10 final will be released in another 8 days. May be you should wait till then instead.
So if you are using Ubuntu 10.04(or early releases) and want to upgrade to new Ubuntu 10.10 RC, hit ALT + F2 and type the following,
update-manager -d
