尝试 sudo apt update 时出现错误

sudo apt update

或者甚至当我使用命令 sudo apt-get update 时：

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

错误2

我还查看了sudo apt update 错误但看起来毫无希望

我还检查了评论中建议的问题答案：

如果存储库/PPA 没有 Release 文件，我该怎么办？

并运行代码

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

sudo apt-get update

但得到了同样的错误

难道我的——点击数：1http://de.archive-- 存在什么问题？

答案1

  1. 转到程序菜单或按下键盘上的窗口来显示它。

  2. 选择软件和更新程序或在菜单中搜索并打开它。

  3. 确保这些选项卡“Ubuntu 软件和更新”中标记了更新选项，您还可以查看同一程序中的其他软件选项卡。

  4. 标记要求密码的框后，单击“关闭”，单击“从新窗口重新加载”并等待其完成更新缓存，然后尝试在终端中更新。
