最近两天为了apt-get update 换源出了很多错误
E: Some index files failed to download. They have been ignored, or old ones used instead
E: Faild to fetch http://ppa.launchpad.net/n-muench/vlc/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found [IP: 91.189.95.83 80]
还有很多未记录，查询给出的答案都是被墙了，地址出错，架构不一样
但怎么改怎么不对，最后找到这个，记录一下
阿里源
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
先提前把你之前的源备份
sudo cp /erc/apt/sources.list/etc/apt/sources.list.back
再换源
sudo gdeit /etc/apt/sources.list
后续问题，这些源里面资源不足
怎么upgrade都不行
再增加这个
sudo add-apt-repository "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe" sudo apt update sudo apt install libjasper1 libjasper-dev
还不是很全直接再添加
