它是 Ubuntu 12.04。我无法更新任何东西。它说“需要安装不受信任的软件包
此操作将需要安装来自未经认证来源的软件包。”
详细信息如下。有人能帮帮我吗？

答案1
请在终端中尝试此命令
sudo apt-get update
这应该可以解决您的问题，如果有任何错误，请与他们一起编辑您的问题。
答案2
仅在 sudo apt-get update 没有帮助的情况下......
在 12.04 中已经有很多更新 - 并且更新管理器本身也更新了几次。
因此，请先尝试：
sudo apt-get install --reinstall update-manager
在你做之前：
sudo apt-get 更新
及之前：
sudo apt-get dist-upgrade
