Ubuntu18.04更换阿里云镜像源文件解决系统无法升级问题

一般我们拿到一台服务器之后第一件事情就应该update升级系统软件库,但是有些时候由于各种的问题,一般是海外主机商会存在这些问题。今天老蒋有遇到这家海外主机商,我在服务器中默认安装的是Ubuntu18.04系统,直接update的时候有出现错误。

Ubuntu18.04更换阿里云镜像源文件解决系统无法升级问题

一般我们用国内主机商是没有这些问题的,应该内置的源是我们国内的。所以这里老 蒋更换阿里云国内的镜像源。

/etc/apt/sources.list

我们可以直接vim编辑文件或者是下载到本地编辑。

将内容替换成:

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

替换之后,我们再执行命令:

apt-get update -y

apt-get upgrade -y

然后我们可以看到没有任何报错。

就这样Ubuntu18.04系统更换源升级软件包是没有问题的,Ubuntu 17.04等版本也是可以使用的。我们如果不放心可以先将系统源文件sources.list备份一份,然后再替换升级,有问题还可以及时恢复。
