如何将GCP更新为最新版本？

Question

我已经运行了一年的VM原型。我好几个月没更新过了。我最近尝试使用sudo apt update更新它。

但是，我得到了以下错误：

我的vm是Google引擎实例。

您使用的Ubuntu发行版似乎已经过时，当这种情况发生时，Ubuntu会更改存储库的服务器。为了能够更新您的发行版，编辑/etc/apt/ change .列表并将archive.ubuntu.com和security.ubuntu.com，更改为old-releases.ubuntu.com.

但是，正如@ Knud所提到的，20.10Groovy被移到了旧版本旧版本/ubuntu.com，而美国-ubuntu 4.gce.Archive.ubuntu.com/ubuntu不适用于“旧的不受支持的”。因此，您将无法将我们- will 4.gce.Archive.ubuntu.com/ubuntu更改为旧版本版本的ubuntu.com。您可以尝试将VM移动到另一个区域/区域并尝试更新版本。

升级ubuntu版本的步骤：

1. 创建服务器或vm的备份。
2. 通过运行sudo apt更新& sudo apt升级命令来升级Ubuntu版本的所有安装包。
3. 通过绑定sudo Reboot命令重新启动Ubuntu系统。
4. 安装update工具，运行：sudo apt安装更新管理器核心.
5. 启动升级过程，运行：sudo发布升级.
6. 重新启动框，运行：sudo重新启动。
7. 确认升级。
