今天在使用星光互联韩国VPS的时候发现源有问题.
问题如下：
E: Release file for http://ftp.kr.debian.org/debian/dists/wheezy-updates/Release is expired (invalid since 1d 6h 32min 3s). Updates for this repository will not be applied
系统发现源有问题,检测修复一下源即可.
解决方案：
Debian:
aptitude -o Acquire::Check-Valid-Until=false update apt-get -o Acquire::Check-Valid-Until=false update
Ubuntu:
sudo aptitude -o Acquire::Check-Valid-Until=false update sudo apt-get -o Acquire::Check-Valid-Until=false update
执行后就可以正常更新了.
