这些bionic、main、restricted、universe、multiverse是什么意思呢该怎么修改才对实在是让人头大。简单了解一下bionic是指你的ubuntu版本代号可以用 lsb_release -c 命令查看
ubuntu 12.04 代号为precise
ubuntu 14.04 代号为trusty
ubuntu 15.04 代号为vivid
ubuntu 15.10 代号为wily
ubuntu 16.04 代号为xenial
ubuntu18.04 代号为bionic
如果不注意这个可能拷贝别人的sources.list文件对应的ubuntu版本和你的不一样就出错了main、restricted、universe、multiverse的意义是
main 即“基本”组件其中只包含符合Ubuntu的协议要求并由Ubuntu团队维护支持的软件。
restricted 即“受限”组件其中包含了非常重要的但并不具有合适的自由协议的软件如显卡驱动同样有 ubuntu团队维护支持。
universe 即“社区维护”组件其中包含的软件种类繁多它们可能采用受限于协议可能不是但都不为ubuntu 团队维护。
multiverse 即“非自由”组件其中包括了不符合自由软体要求而且不被Ubuntu团队支援的软件通常为商业公司编写的软件。其实不必了解他们的具体含义最好的方法就是不改动它们保持原样只改动url部分观察到我的sources.list中url均为http://ports.ubuntu.com/ubuntu-ports
那么改为阿里云的镜像节点URL就行了
http://mirrors.aliyun.com/ubuntu/可是改了以后apt update仍然出现了很多404错误查看错误信息才发现阿里云的镜像节点 http://mirrors.aliyun.com/ubuntu/ 只包含x86 x64的bin并不包含arm的bin怎么会这样呢难道阿里云偷懒了吗只拷贝了PC版ubuntu需要的包
后来才发现不是这样的是URL路径不对应该改为 http://mirrors.aliyun.com/ubuntu-ports重点
所以直接生搬硬套copy网上的资料是有可能会出问题的最好最简单最靠谱的办法就是打开你原本的/etc/apt/sources.list 只替换其中的host部分其它部分一个字符都不要动
sudo vim /etc/apt/sources.list
:%s/ports.ubuntu.com/mirrors.aliyun.com/g
:wq
