目录
以Ubuntu18.04为例：
1. 备份原有软件源文件
cp /etc/apt/sources.list /etc/apt/sources.list.bak_yyyymmdd
2. 打开sources.list文件，在文件末尾增加如下软件源地址
vi /etc/apt/sources.list
追加如下地址：
#添加阿里源

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

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
3. 更新系统软件源
执行命令，更新系统软件源地址
apt-get update
apt-get upgrade
Xubuntu15.04更新系统源时出现错误提示W: GPG 错误：http://archive.ubuntukylin.com:10006 xenial InRelease: 由于没有公钥，无法验证
在更新系统源后，输入sudo apt-get update之后出现提示：
W: GPG 错误：http://archive.ubuntukylin.com:10006 xenial InRelease: 由于没有公钥，无法验证下列签名： NO_PUBKEY 8D5A09DC9B929006
W: GPG 错误：http://ppa.launchpad.net vivid InRelease: 由于没有公钥，无法验证下列签名： NO_PUBKEY C2518248EEA14886
解决方法：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8D5A09DC9B929006
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C2518248EEA14886
