Ubuntu系统自带的是国外的源,咱们国内用户使用的时候下载文件特别的慢,所以我们需要更换国内镜像源,这里我列举两个换源的方法,如果有新的方法可以在评论区补充。
首先第一步
我们需要更改root密码
sudo passwd root
命令行:
首先备份源
也可以不备份
sudo cp /etc/apt/sources.list /etc/apt/sources.list.old
打开源
sudo gedit /etc/apt/sources.list
将阿里云镜像全选,复制进去
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
保存并退出
sudo apt-get update #这个命令会访问源列表里的每个网址，并读取软件列表，将其保存在本地
sudo apt-get upgrade #这个命令会更新本地已安装的软件
图形化
进入下角软件库,打开软件和更新
选择其他站点
选择阿里云
选择完之后需要在更新下软件库
sudo apt-get update
sudo apt-get upgrade
