雲服務器更換軟件源

騰訊雲鏡像

• 騰訊雲的官方鏈接：
  目前騰訊雲軟件源站支持公網訪問和內網訪問。
  公網訪問地址：http://mirrors.cloud.tencent.com/
  內網訪問地址：http://mirrors.tencentyun.com/
  然後找到對應最新系統版本的鏡像源即可，這裏找了下Ubuntu16.04的軟件源：

deb http://mirrors.cloud.tencent.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.cloud.tencent.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.cloud.tencent.com/ubuntu/ xenial-updates main restricted universe multiverse
#deb http://mirrors.cloud.tencent.com/ubuntu/ xenial-proposed main restricted universe multiverse
#deb http://mirrors.cloud.tencent.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.cloud.tencent.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.cloud.tencent.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.cloud.tencent.com/ubuntu/ xenial-updates main restricted universe multiverse
#deb-src http://mirrors.cloud.tencent.com/ubuntu/ xenial-proposed main restricted universe multiverse
#deb-src http://mirrors.cloud.tencent.com/ubuntu/ xenial-backports main restricted universe multiverse

也可以通過wget進行下載：

# 16.04
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
sudo wget -O /etc/apt/sources.list http://mirrors.cloud.tencent.com/repo/ubuntu16_sources.list
# 更新緩存
suod apt-get clean all
sudo apt-get update
