        經常在yum update的時候遇到類似與這樣的問題：

                     Error: Package:  *****************************

                                 Requires: ******************************

                                 Removing:  xxxxxxxxxxx.x86_64   (@rpmforge)   ****** 

                                 Updated By:   *******-*****-***********    Not find                                             

                          You could try using --skip-broken to work around the problem
                          You could try running: rpm -Va --nofiles --nodigest

                       如：

                   

         解決辦法：

                      將xxxxxxx-xxxxx-xxxx.x86_64卸載掉： yum remove xxxxx-xxxxx-xxxxxxx.x86_64

                      然後就可以yum update了!

                      應該是xxxxxxx-xxxxx-xxxxxxx.x86_64的epel更新源找不到，導致整個yum update不能用。

                      如果需要的話再將卸載掉的xxxxxx(去掉版本號等部分(-xxxxx-xxxxxxx)，重新索源安裝，儘量避免再次導致同源找不到的問題）重新安裝： yum install xxxxxx
