我下DNF的时候`安装的时候出现的`
The installer you are trying to use is corrupted or incomplete.
This could be the result fo a damaged disk,a failed download or a virus.
You may want yo contact the author fo this installer to obtain a new copy.
It may be possible to skip this check using the /ncrc command line switch
(NOT RECOMMENDED).
希望高手给个解决方法`说通俗点`复制的别来`要针对安装DNF的
