Ubuntu仓库没有Release文件。

16.04aptupdatesrepository
这与Xenial repository does not have a Release file类似，但那里的修复方法对我无效。
在一个几天前安装的Ubuntu 16.04上运行sudo apt-get update时，会返回以下错误信息：

我已经尝试过使用sudo rm /var/lib/apt/lists/*命令，而且我的/etc/apt/sources/list文件中已经注释掉了第52行，并且第54行并不存在。（这两个解决方案都是我在这个论坛和其他论坛上找到的）。
请问您能否编辑一下您的问题，包括完整的终端命令输出“LC_MESSAGES=POSIX apt-get update”？谢谢。 - David Foerster
@DavidFoerster 给你。 - Adoria298
http://archive.ubuntu.com xenial Release 没有指向现有软件包仓库。请您[编辑]问题，包括 /etc/apt/sources.list 的内容以及 grep -nwFe Release /etc/apt/sources.list{,.d/*.list} 的输出。 - David Foerster
@DavidFoerster 添加了您所要求的内容。 - Adoria298
7对于投票关闭的人：我不明白这个问题怎么会不清楚。 - Gunnar Hjalmarsson
6个回答
你的 /etc/apt/sources.list 文件中倒数第三行似乎有错误：
deb http://archive.ubuntu.com xenial universe

我认为那一行代码是导致错误的原因，所以我建议你将其删除。
在这样做之后，可能需要清理软件包缓存，你可以通过运行以下命令来完成：
sudo rm -r /var/lib/apt/lists/*

然后：
sudo apt update
8我已经投票支持重新开放上述问题，该问题被错误地关闭，原因是不清楚，但实际上并非如此。 - karel
2我遇到了同样的错误。似乎是因为Ubuntu 17.04现在不再受支持。https://wiki.ubuntu.com/ZestyZapus/ReleaseNotes - Morgan Christiansson
1@MorganChristiansson：对我来说，这听起来像是一个不同的问题，即使错误信息看起来相似。 - Gunnar Hjalmarsson
使用nano编辑并删除了所述行后，现在运行sudo apt-get update会返回E: 软件包缓存文件已损坏。 - Adoria298
1@Adoria298：请查看我的修改后的答案。 - Gunnar Hjalmarsson
@GunnarHjalmarsson 运行了这两个命令后，出现了相同的错误。 - Adoria298
@Adoria298: 如果你也运行 sudo rm /var/lib/apt/lists/partial/*，会有什么区别吗？如果没有的话，请再次编辑你的问题，并展示完整的 sudo apt update 输出。 - Gunnar Hjalmarsson
@GunnarHjalmarsson 很抱歉，请您能否看一下我编辑过的问题。 - Adoria298
@Adoria298：E: 读取错误 - 读取（5: 输入/输出错误）表示某种硬件问题，这超出了我的能力范围，与你最初的问题完全无关。如果问题持续存在，并且你需要进一步调查的指导，请建议你发布一个新的问题。 - Gunnar Hjalmarsson
@GunnarHjalmarsson 好的 - Adoria298
请注意，有时候解决方案只是删除缓存，可能是因为在最近的更新中您使用了代理。 - tuxErrante
在我的情况下，问题真的很愚蠢。我在服务器外没有网络访问权限。花了我相当长的时间才意识到这是我的问题；-)
4老实说，“没有发布文件”并不是应该传达的信息。它得出了一个结论，而不是陈述事实。“无法下载发布文件”才是准确的表达。这不是你的错，是别人的错。谢谢你分享这个“傻呵呵”的时刻。 ;) - TheSatinKnight
在我的情况下（16.04 LTS），远程下载服务器可能存在一些问题。我收到了一个未记录的错误通知。我更改了下载服务器，问题得到解决。我已经在另一篇帖子中记录了这个解决方案。
在Linux Mint（Ubuntu的子版本）上，问题出现在软件源->附加仓库中。安装的软件添加了一个错误版本操作系统的仓库。 - Andrew
这是在尝试安装一个没有适用于您的Ubuntu版本的软件包时常见的错误...所以解决方案是更新您的/etc/apt文件，使用先前版本的Ubuntu（顶级提示：如果您的机器的Ubuntu版本不是最新的Ubuntu LTS https://releases.ubuntu.com，则更新下面提到的文件以使用该软件包的LTS版本）。
例如，我正在使用的是Ubuntu 20.10。
 cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.10
DISTRIB_CODENAME=groovy
DISTRIB_DESCRIPTION="Ubuntu 20.10"

我看到下面的错误。
Hit:11 http://archive.ubuntu.com/ubuntu groovy-backports InRelease  
Hit:12 http://archive.ubuntu.com/ubuntu groovy-security InRelease

Reading package lists... Done
E: The repository 'https://packages.microsoft.com/repos/azure-cli groovy Release' does not have a Release file.
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.

这意味着该软件包没有适用于我的操作系统版本（groovy）的版本（通常情况下，软件包不会为每个Ubuntu版本提供发布版本），因此只需更新安装文件以使用先前的Ubuntu版本（良好的建议是使用最新的长期稳定版本LTS，请参见https://releases.ubuntu.com/）。
因此，由于我的机器是Ubuntu 20.10（groovy），而LTS是20.04（focal），只需通过以下方式更新，停止使用groovy，并改为使用focal...如下所示：

每两年Ubuntu都会发布一个新的LTS版本，总是在偶数年，并且只针对xx.04版本进行发布。

cd /etc/apt
grep -r azure-cli # to find offending file responsible for error

显示
sources.list.d/azure-cli.list:deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ groovy main

编辑上述文件。
sudo vi /etc/apt/sources.list.d/azure-cli.list

将提及的groovy替换为focal 
cat /etc/apt/sources.list.d/azure-cli.list

# deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ groovy main
deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ focal main

好了...现在你的机器已经指向了一个好的源，让我们安装这个软件包。
sudo apt-get install azure-cli  #
可以设置代理。
请查看以下位置：
- /etc/apt/apt.conf - /etc/apt/apt.conf.d - http_proxy 环境变量
尝试这两个命令：
sudo snap install cmake --classic
cmake --version

他们为我工作。
