On my second attempt to upgrade 12.04 to 12.10 I can report that things were successful and so far limited bugs but I guess that is to be expected since not to much work on 12.10 has occurred so far.
Will you upgrade to 12.10 before it hits Alpha 1? I have ran each release prior to Alpha 1 and have had limited issues and if you want to join me in running bleeding edge (highly discouraged and especially if you are using PPA’s) then you can simply run the following from terminal:
sudo sed -i ‘s/precise/quantal/g’ /etc/apt/sources.list
sudo apt-get update && sudo apt-get dist-upgrade
and you should get something like this after upgrade and reboot…
