Linux arm64架构修改软件源 （统信UOS，麒麟系统修改阿里源、华为源） 国产系统UOS修改apt源_统信软件源

步骤：备份原来自带的软件源—>修改软件源配置文件—>处理报错（公钥问题）—>清理缓存—>更新缓存—>安装软件

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，速度快，推荐）

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（arm64,速度快，二者选其一）

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

命令：apt-get update

可能出现报错

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
