Apt Authentication issue

Problem during package list update. The package list update failed with a authentication failure. This usually happens behind a network proxy server. Please try to click on the "Run this action now" button to correct the problem or update the list manually by running Update Manager and clicking on "Check".

在执行完check后，还是会出现这样的错误，解决方法：
