我在我们的服务器上升级到 Ubuntu Bionic，但它要求我升级到 Xenial？

Question

这是我通过 SSH（无控制台 - 远程）登录时，这是Ubuntu 18.04 Bionic。我已经重新启动了很多次，我做了do-release-upgrade，它说我应该升级到Xenial吗？怎么来的？2-3 年前，我从14.04升级到16.04，然后从16.04升级到18.04，所以现在，我在18.04，然后它仍然说我应该升级到Xenial作为sudo apt-get install linux-generic-lts-xenial

我的输出是这样的：

You have packages from the Hardware Enablement Stack (HWE) installed that
are going out of support on 2016-08-04.

To upgrade to a supported (or longer-supported) configuration:

* Upgrade from Ubuntu 14.04 LTS to Ubuntu 16.04 LTS by running:
sudo do-release-upgrade 

OR

* Switch to the current security-supported stack by running:
sudo apt-get install linux-generic-lts-xenial

and reboot your system.

怎么来的？

Answer 1

检测 HWE 支持的脚本似乎与剩余的内核包混淆。

您可以以 root 身份运行“hwe-support-status --show-all-unsupported”来确定系统中存在哪些剩余的包，然后在每个包上运行“apt --purge remove”以删除它们。

之后，您不应再看到此消息。
