ubuntu 更換國內源

安裝好ubuntu系統後，預設的軟體更新源是國外的，在國內使用速度很慢，用"apt install ***"安裝軟體時可能出現"網路不可達"、"你的網路需要認證嗎"、"無法定位軟體包"等錯誤，所以我們需要更換成國內的源，這樣才能正常安裝和更新軟體。

桌面開啟終端，執行命令：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
執行命令， 開啟檔案進行編輯；
sudo gedit /etc/apt/sources.list

刪除原來的檔案內容，複製【軟體源映象】到其中並儲存；

linux20.04：


# 預設注釋了原始碼映象以提高 apt update 速度，如有需要可自行取消注釋


deb focal main restricted universe multiverse


# deb-src focal main restricted universe multiverse


deb focal-updates main restricted universe multiverse


# deb-src focal-updates main restricted universe multiverse


deb focal-backports main restricted universe multiverse


# deb-src focal-backports main restricted universe multiverse


deb focal-security main restricted universe multiverse


# deb-src focal-security main restricted universe multiverse


# 預發布軟體源，不建議啟用


# deb focal-proposed main restricted universe multiverse


# deb-src focal-proposed main restricted universe multiverse
linux18.04：


# 預設注釋了原始碼映象以提高 apt update 速度，如有需要可自行取消注釋


deb bionic main restricted universe multiverse


# deb-src bionic main restricted universe multiverse


deb bionic-updates main restricted universe multiverse


# deb-src bionic-updates main restricted universe multiverse


deb bionic-backports main restricted universe multiverse


# deb-src bionic-backports main restricted universe multiverse


deb bionic-security main restricted universe multiverse


# deb-src bionic-security main restricted universe multiverse


# 預發布軟體源，不建議啟用


# deb bionic-proposed main restricted universe multiverse


# deb-src bionic-proposed main restricted universe multiverse
終端執行命令：

sudo apt update
更新軟體列表，換源完成。
