Ubuntu 20.04 上的 sudo apt update

Question

我將 Ubuntu 安裝在外在硬碟上

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:    22.04
Codename:   jammy

嘗試 sudo apt update 時出現錯誤

sudo apt update
Hit:1 http://security.ubuntu.com/ubuntu jammy-security InRelease
Hit:2 http://de.archive.ubuntu.com/ubuntu jammy InRelease                                      
Hit:3 http://deb.anydesk.com all InRelease                                                     
Ign:4 http://packages.ros.org/ros/ubuntu jammy InRelease                 
Err:5 http://packages.ros.org/ros/ubuntu jammy Release
  404  Not Found [IP: 64.50.233.100 80]

E: The repository 'http://packages.ros.org/ros/ubuntu jammy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

W: http://deb.anydesk.com/dists/all/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

或甚至當我使用命令 sudo apt-get update 時：

sudo apt-get update
Hit:1 http://deb.anydesk.com all InRelease
Hit:2 http://de.archive.ubuntu.com/ubuntu jammy InRelease

我還檢查了說明sudo apt update 錯誤但看起來毫無希望

我還檢查了評論中建議的問題答案：

如果儲存庫/PPA 沒有發布文件，我該怎麼辦？

並運行程式碼

sudo add-apt-repository --remove ppa:mc3man/trusty-media

sudo apt-get update

但得到了同樣的錯誤

難道我的--命中：1http://de.archive-- 是問題所在嗎？

Answer 1

1. 轉到程式選單或按鍵盤上的 windows 來顯示它。

2. 選擇軟體和更新程式或在選單中搜尋它以顯示並打開它。

3. 確保這些標籤中標記了更新選項“Ubuntu 軟體和更新”，您也可以查看同一程式中的其他軟體標籤。

4. 標記將詢問密碼的框後，按一下“關閉”，按一下從新視窗重新載入並等待其完成更新緩存，然後嘗試在終端機中更新。
