近日博主买了台VPS，装了个Debian 10，使用apt-get update后出现源报错：
Get:1 http://deb.debian.org/debian buster InRelease [122 kB]
Get:2 http://security.debian.org/debian-security buster/updates InRelease [34.8 kB]
Get:3 http://deb.debian.org/debian buster-updates InRelease [56.6 kB]
Reading package lists... Done

在更新前执行以下命令：
apt-get --allow-releaseinfo-change update这个命令的意思是，允许更新命令继续从改变了版本库信息的版本库中下更新源。
然后再执行apt-get update就不会出错了。
