腾讯云ubuntu20.04 安装5.7Xmysql
作者：互联网
1. 换源
如果出现下面的问题就换源，估计都会出现，因为5.7版本在ubuntu20.04中太老了，然后腾讯云源镜像不好用
E: Failed to fetch http://mirrors.tencentyun.com/ubuntu/pool/universe/n/ncurses/libtinfo5_6.2-0ubuntu2_amd64.deb Something wicked happened resolving 'mirrors.tencentyun.comaddress associated with hostname)
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
备份
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
更改文件权限使其可编辑
sudo chmod 777 /etc/apt/source.list
vim /etc/apt/sources.list
