1.ubuntu软件源

步骤1：打开/etc/apt/sources.list

sudo gedit /etc/apt/sources.list

步骤2：在文件中添加如下软件源

步骤3：更新软件源目录

sudo apt-get update 

 2.Centos软件源

以阿里源为例

步骤1：先将原文件备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak

步骤2：下载阿里源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

centos-x：需要几就把数字为几

步骤3：建立cache及其更新源包

yum makecache
yum -y update

其他：海康软件源centos-7：

修改

vi /etc/yum.repos.d/CentOS-Base.repo

如下： 

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
