但是每次仍然会出现相同的错误：

Reading package lists... Done
W: GPG error: http://archive.canonical.com precise Release:
 The following signatures were invalid: 630239CC130E1A7FD81A27B140976EAF437D05B5
E: The repository 'http://archive.canonical.com precise Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore
 disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

第一次尝试：

ahadji05@ahadji05-UX330UAR:~$ gpg --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192
gpg: key 16126D3A3E5C1192: 3 signatures not checked due to missing keys

gpg: no ultimately trusted keys found
gpg: Total number processed: 1

ahadji05@ahadji05-UX330UAR:~$ gpg --export --armor 16126D3A3E5C1192 | sudo apt-key add -
OK

ahadji05@ahadji05-UX330UAR:~$ sudo apt-get update

然后我尝试了这个：

在所有的情况下，我都得到了相同的错误...

- Andreas Hadjigeorgiou

Ubuntu 版本是什么？precise 是 12.04，已经到了 EoL（终止支持）的阶段。 - Pilot6

ahdji05@ahdji05-UX330UAR:~$ lsb_release -a 没有可用的LSB模块。发行商ID：Ubuntu 描述：Ubuntu 18.04.2 LTS 版本：18.04 代号：bionic - Andreas Hadjigeorgiou

1编辑/etc/apt/sources.list文件并删除包含precise的行。也可以在“软件和更新”图形界面中完成。 - Pilot6

如果我这样做，它会起作用，但是我以这种方式是否会得到所有的更新呢？或者我会失去一些东西吗？ - Andreas Hadjigeorgiou

1你不会损失任何东西。这行代码是错误的。你可能运行了一些在网络上找到的过时命令。 - Pilot6

1你可以将cat /etc/apt/sources.list的输出发布到你的问题中，以使其更清晰明了。 - Pilot6

Pilot6上面的回答解决了我的问题。我已经编辑了帖子，并包含了之前遇到的所有错误。 - Andreas Hadjigeorgiou

OP可能运行了一些命令，却不知道它的作用。 - Pilot6

我没有添加任何东西，它本来就在那里。这是我第一次访问此文件：/etc/apt/source.list - Andreas Hadjigeorgiou

从`sources.list`中删除过时的软件源

这个问题涉及到Ubuntu 18.04，Bionic。OP错误地添加了一个已经到达生命周期末期的Ubuntu 12.04，Precise的过时软件源。这个过时的软件源已经不存在了，导致出现以下错误：

E: The repository 'http//archive.canonical.com precise Release' is not signed.

解决方法是从sources.list中删除有问题的行。

GUI方法：

打开“软件和更新”程序。

然后转到“其他软件”选项卡：

找到每一行上有precise的内容。逐行突出显示。在窗口底部按下Remove按钮。

对所有包含precise的行重复此操作。这些行是指Ubuntu 12.04的过时存储库。您正在使用Ubuntu 18.04，这是目前支持的版本之一。

命令行方法：

按下Ctrl+Alt+T打开终端，然后输入：

sudo nano /etc/apt/sources.list

现在您将能够编辑sources.list文件。寻找以下行：

deb http://archive.ubuntu.com/ubuntu precise Release

删除这行和任何其他带有precise的行。

通过按下Ctrl+X退出nano编辑器。编辑器将提示您保存更改。按下Y，然后按下Enter选择默认文件名。

希望这对您有所帮助。
