ubuntu更換軟件源方法

轉載部分內容：

這些bionic、main、restricted、universe、multiverse是什么意思呢，該怎么修改才對，實在是讓人頭大。簡單了解一下：bionic是指你的ubuntu版本代號，可以用 lsb_release -c 命令查看： ubuntu 12.04 代號為precise ubuntu 14.04 代號為trusty ubuntu 15.04 代號為vivid ubuntu 15.10 代號為wily ubuntu 16.04 代號為xenial ubuntu18.04 代號為bionic 如果不注意這個，可能拷貝別人的sources.list文件對應的ubuntu版本和你的不一樣，就出錯了main、restricted、universe、multiverse的意義是： main 即“基本”組件，其中只包含符合Ubuntu的協議要求并由Ubuntu團隊維護支持的軟件。 restricted 即“受限”組件，其中包含了非常重要的，但并不具有合適的自由協議的軟件，如顯卡驅動，同樣有 ubuntu團隊維護支持。 universe 即“社區維護”組件，其中包含的軟件種類繁多，它們可能采用受限于協議，可能不是，但都不為ubuntu 團隊維護。 multiverse 即“非自由”組件，其中包括了不符合自由軟體要求而且不被Ubuntu團隊支援的軟件，通常為商業公司編寫的軟件。其實不必了解他們的具體含義，最好的方法就是不改動它們，保持原樣，只改動url部分，觀察到我的sources.list中，url均為：http://ports.ubuntu.com/ubuntu-ports 那么改為阿里云的鏡像節點URL就行了： http://mirrors.aliyun.com/ubuntu/可是改了以后，apt update仍然出現了很多404錯誤，查看錯誤信息才發現阿里云的鏡像節點 http://mirrors.aliyun.com/ubuntu/ 只包含x86 x64的bin，并不包含arm的bin，怎么會這樣呢，難道阿里云偷懶了嗎？只拷貝了PC版ubuntu需要的包？ 后來才發現不是這樣的，是URL路徑不對，應該改為 http://mirrors.aliyun.com/ubuntu-ports重點 所以，直接生搬硬套copy網上的資料，是有可能會出問題的，最好，最簡單，最靠譜的辦法，就是打開你原本的/etc/apt/sources.list 只替換其中的host部分，其它部分一個字符都不要動 sudo vim /etc/apt/sources.list :%s/ports.ubuntu.com/mirrors.aliyun.com/g :wq sudo apt updateperfect !
