本文介绍华为arm架构主机使用国内源配置

1.备份系统之前的源

cp /etc/apt/sources.list /etc/apt/sources.list.bak

2.修改源文件/etc/apt/sources.list

vim /etc/apt/sources.list

将原来的内容删除，将下面的源内容粘贴上。
这里推荐比较好的两个国内源

1. 阿里源（arm64）

deb http://mirrors.aliyun.com/ubuntu-ports/ xenial main
deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial main
 
deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates main
deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates main
 
deb http://mirrors.aliyun.com/ubuntu-ports/ xenial universe
deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial universe
deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates universe
deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates universe
 
deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-security main
deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-security main
deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-security universe
deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-security universe

2. 华为源

机型为华为推荐使用此源

deb https://repo.huaweicloud.com/ubuntu-ports/ bionic main restricted universe multiverse
deb-src https://repo.huaweicloud.com/ubuntu-ports/ bionic main restricted universe multiverse
 
deb https://repo.huaweicloud.com/ubuntu-ports/ bionic-security main restricted universe multiverse
deb-src https://repo.huaweicloud.com/ubuntu-ports/ bionic-security main restricted universe multiverse
 
deb https://repo.huaweicloud.com/ubuntu-ports/ bionic-updates main restricted universe multiverse
deb-src https://repo.huaweicloud.com/ubuntu-ports/ bionic-updates main restricted universe multiverse
 
deb https://repo.huaweicloud.com/ubuntu-ports/ bionic-backports main restricted universe multiverse
deb-src https://repo.huaweicloud.com/ubuntu-ports/ bionic-backports main restricted universe multiverse
 
## Not recommended
# deb https://repo.huaweicloud.com/ubuntu-ports/ bionic-proposed main restricted universe multiverse
# deb-src https://repo.huaweicloud.com/ubuntu-ports/ bionic-proposed main restricted universe multiverse

3. 处理报错
   使用命令

apt-get update

可能出现报错

使用以下命令解决

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 40976EAF437D05B5 3B4FE6ACC0B21F32

4. 清除软件仓库缓存

apt-get clean

5. 更新软件仓库

apt-get update

完成，apt-get install 应用名 就可以安装应用了
