ubuntu19.10更改国内镜像源(附其他版本ubuntu换源教程,史上最全!)

ubuntu又双叕更新啦!安装好ubuntu双系统或者ubuntu虚拟机之后,默认的软件更新源是国外的,在国内使用速度很慢,用"apt install"安装软件时各种网络问题层出不穷,因此我们需要更换成国内的源,这样才能正常安装和更新软件。

首先将我们的原来的软件源另存起来备份:

sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.backup

终端执行chmod命令更改文件权限使软件源文件可编辑:

sudo chmod 777 /etc/apt/sources.list

之后通过gedit命令编辑软件源:

sudo gedit /etc/apt/sources.list

然后将下面任意一个源复制进去保存就好了:

修改完软件源后,更新软件列表和软件:

sudo apt update

sudo apt upgrade

注意:“eoan”为ubuntu版本名!“eoan”代表ubuntu19.10,“xenial”代表ubuntu16.04,“bionic”代表ubuntu18.04,“disco”代表ubuntu19.04,如果自己的版本不再所描述的上面,可以通过查看,并更改相应位置就ok了!

lsb_release -c
