Ubuntu 16.10更新问题（某些存储库yakkety版本没有Release）

也有类似的消息（“ Ubuntu存储库没有发布文件” ...，但对我而言无效）。

我尝试更新系统（apt-get更新），但是出现一些错误。

具体而言（主要错误）：[CODE] E：存储库“ http://archive.ubuntu.com/ubuntu yakkety Release”没有发布文件。W：无法安全地从这样的存储库进行更新， W：因此请参见apt-secure（8）联机帮助页以创建存储库和用户配置详细信息。E：存储库“ http://archive.ubuntu.com/ubuntu yakkety-updates版本”不拥有发布文件。W：无法安全地从这样的存储库进行更新，因此默认情况下被禁用。W：有关存储库创建和用户配置的详细信息，请参见apt-secure（8）联机帮助页。E：存储库“ http://archive.ubuntu.com/ubuntu yakkety-security版本”没有发布文件。[/码]

我的Ubuntu版本：说明：Ubuntu 16.10代号：yakkety

我尝试了许多在不同线程和不同来源中找到的解决方案，例如：sudo apt-get autoclean sudo apt-get clean sudo apt-get update

我从“软件和更新”的“其他软件”中禁用了所有PPA（以防万一。）。

而且，我评论了一对sources.list文件（仅尝试使用）：

...但主要错误仍然存​​在（请参见顶部的“主要错误”）...

当我尝试：sudo apt-get update

我懂了 ：

有任何想法吗？提前致谢！

Ubuntu 16.10自2017年7月20日起停产。

更改http://archive为http://old-releasesin /etc/apt/sources.list文件，然后运行

sudo apt update && sudo apt upgrade

再次。

然后更新到受支持的版本。
