What is the recommended method for getting & installing updates for an Ubuntu (alpha or) beta release?
I've installed 11.10 Alpha2 in a virtual machine (Virtualbox). I know there are updates since i installed it, about a week ago, but when i try sudo apt-get upgrade
or sudo apt-get dist-upgrade
it doesn't find any updates.
So my question, is there any special way for upgrading alpha releases? What about betas?
