正如您所看到的，ping 解析主机名：

~$ ping security.ubuntu.com

需要明确的是，我在 Ubuntu 服务器上打开了自动更新，这是最近发生的（过去一周或两周）。请帮忙！

Answer 1

Impish 于 7 月 14 日停产。因此，在镜像上无法再找到它的存储库，因此如果您想继续使用此版本，则需要将old-releases.ubuntu.com其用作镜像。

但请注意，Impish 将不再有升级，因此您可能需要切换到受支持的版本。最简单的升级方法是运行以下命令：do-release-upgrade

Answer 2

我尝试了这个（在RPI3，Ubuntu 21.10上），修改/etc/apt/sources.list

deb http://ports.ubuntu.com/ubuntu-ports impish main restricted

到

deb http://old-releases.ubuntu.com/ubuntu impish-security main restricted

对所有条目执行相同的操作（首先复制）

然后

sudo apt update
sudo apt upgrade

就我而言，升级成功。

然后我尝试了

sudo do-release-upgrade 

这失败了：

Checking for a new Ubuntu release
Your Ubuntu release is not supported anymore.
For upgrade information, please visit:
http://www.ubuntu.com/releaseendoflife

You have not rebooted after updating a package which requires a reboot. Please reboot before upgrading.

所以稍后重新启动一次

sudo do-release-upgrade 

= 欢迎使用 Ubuntu 22.04 'Jammy Jellyfish' =

Ubuntu 团队很自豪地发布 Ubuntu 22.04“Jammy Jellyfish”。

要了解此版本中的新增功能，请访问： https: //wiki.ubuntu.com/JammyJellyfish/ReleaseNotes

And I continued with the dist upgrade

Hope this helps
