ubuntu - 如何解决在 Linux 上安装 Minikube for Kubernetes 时出现的错误

Question

我正在尝试在本地为 Kubernetes 安装 minubuke。我尝试使用 sudo grep -E --color 'vmx|svm' /proc/cpuinfo 在我的 Linux PC 上确认虚拟化我得到了这个错误:

vmx flags   : vnmi preemption_timer invvpid ept_x_only flexpriority tsc_offset vtpr mtf vapic ept vpid unrestricted_guest

我尝试通过运行 sudo apt-get update 对问题进行排序我在下面收到此错误:

我真的不知道该怎么办，请任何人帮忙，我将不胜感激。谢谢。

如何检查处理器是否支持虚拟化技术。
您应该查看 flags /proc/cpuinfo 中的部分两个可能值之一的文件:虚拟机 (英特尔)或 svm (AMD)。
您可以使用 grep 代替手动检查此文件。与您的情况一样的命令:

$ sudo grep -E --color 'vmx|svm' /proc/cpuinfo

在您的输出中，您可以找到 虚拟机 (英特尔-VT 技术):

flags       : ... vmx ...

这意味着您的 CPU 支持虚拟化技术。
修复更新包列表时的 404 错误。

E: The repository 'http://ppa.launchpad.net/ozmartian/apps/ubuntu focal Release' does not have a Release file.

上面的错误告诉您，此存储库不适用于您当前的 Ubuntu 版本。
您可以在此 article 中找到详细说明和可能的解决方法.此外，还有一个类似的 problem with accepted answer .
简而言之，您可以使用以下方法删除此存储库:

$ sudo add-apt-repository -r http://ppa.launchpad.net/ozmartian/apps/ubuntu

然后更新包列表:

$ sudo apt update
