正在解决依赖关系
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don‘t work you‘ll have to try removing/installing packages by hand (maybe package-cleanup can help).
