Debian源更新报错解决方法

今天更新debian 10的源的时候，突然报错，主要是说源从稳定源切换到不稳定源，连忙查了一下原因。

'Suite' value from 'stable' to 'oldstable'

root@debian:# apt-get update
Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB]
Get:2 http://deb.debian.org/debian buster InRelease [122 kB]

还好，运行下面的命令成功解决。

apt-get --allow-releaseinfo-change update

再次更新源，如下：

root@debian:# apt-get --allow-releaseinfo-change update
Hit:1 http://security.debian.org/debian-security buster/updates InRelease
Hit:2 http://deb.debian.org/debian buster InRelease
Hit:3 http://deb.debian.org/debian buster-updates InRelease
Hit:4 http://nginx.org/packages/mainline/debian buster InRelease

root@debian:# apt-get update
Hit:1 http://security.debian.org/debian-security buster/updates InRelease
Hit:2 http://deb.debian.org/debian buster InRelease
Hit:3 http://deb.debian.org/debian buster-updates InRelease
Hit:4 http://nginx.org/packages/mainline/debian buster InRelease

--allow-releaseinfo-change

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。
