升级中出现的提示!!
No valid mirror found

While scaning your repository information no mirror entry for the upgrade was found.This cam happen if you run a internal mirror or if the mirror information is out of date.

Do you want to rewrite your 'sources.list' file anyway? If you choose 'Yes' here it will update all 'breezy' to 'dapper' entries.
If you select 'no' the update will cancel.
还有这个提示！！
Error authenticating some packages

It was not possible to authenticate some packages. This may be a transient network problem. You may want to try again later. See below for a list of unauthenticated packages.

照这个去做吧，如果实在不行，重装－－最后的办法。
