安装好Ubuntu,首先第一步,要更换源否则… … Ubuntu中大部分的软件安装和更新都是利用apt命令从Ubuntu的服务器直接安装的。 Ubuntu官方的服务器在国外为了提高软件安装和更新速度Ubuntu提供了选择最佳服务器的功能可以帮助我们方便的找到一个速度最快的镜像服务器 试错无数次这里我推荐 清华大学开源软件镜像站 中国科学技术大学 例如中国科学技术大学可使用配置生成器生成各Ubuntu版本的镜像源。 1. 备份镜像源设置文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak2. 编辑镜像源设置文件
sudo gedit /etc/apt/sources.list3. 更新源及/etc/apt/sources.list
sudo apt-get update 4. 更新已安装的软件包
sudo apt-get upgrade 6. 将复制对应版本的清华源或科大源复制粘贴到打开的编辑文档 7. 这是ubtuntu自带sources.list
如要退回原来的源复制粘贴即可。
