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。
