Problems with upgrading fedora16beta

I directly preupgrade from f15 and it was quite smooth. I encountered a small problem. I was unable to log on. I just installed it and restarted it. I found that the black logon interface had changed, but the password I entered was always Oh, No, SomeProblem ..... My God, I cannot go in. Fortunately, I have other accounts...

I directly preupgrade from f15 and it was quite smooth. I encountered a small problem.

1. logon failure:

After the installation, restart and find that the black logon interface has changed, but the password is always Oh, No, Some Problem ..... My God, I cannot go in. Fortunately, I still have other accounts (oracle). after going in, I moved all the hidden files under my original account ~ In the/tmp Directory, log on. It is estimated that this problem is my previous configuration of the content, the new gnome-3.1.9x does not recognize.

II. upgrade failed

Software update tools fail. I use yum-complete-transaction, and the output similar to an endless loop appears on the system. Fortunately there is yumex. I used him to update the software in three batches, and finally found that it was libgcc, libstdc ++, and so on. Use the yum-complete-transaction command to check whether the unfinished transaction is abandoned or disabled, and no more (I should have done some using yumex ).

Then, yum update fails, and the following error occurs: Protected multilib versions. After you google it online, use yum upgrade -- setopt = protected_multilib = false. But yum list libgcc still has two versions, and finally it is still to be turned into his nest, yum remove libgcc-4.6.1-9.fc16.x86_64 a command to solve.
