出厂的镜像源是
deb http://mirrors.163.com/ubuntu-ports focal main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu-ports focal main restricted universe multiverse
为了加快更新包的速度,我们通常要更换镜像源,更换方法如下:
1、备份原来的源的文件/etc/apt/sources.list。
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
2、sudo wget -O /etc/apt/sources.list https://repo.huaweicloud.com/repository/conf/Ubuntu-Ports-bionic.list
这样就换成了华为的源。
修改后保存。然后执行apt update速度就快很多了。
