如何解決在 Linux 上為 Kuberntes 安裝 Minikube 時出現的錯誤

Question

我正在嘗試在本地為 Kubernetes 安裝 minubuke。 我嘗試使用此sudo grep -E --color 'vmx|svm' /proc/cpuinfo在我的 Linux PC 上確認虛擬化，但出現此錯誤：

我嘗試通過運行sudo apt-get update對問題進行排序，但出現以下錯誤：

我真的不知道該怎么辦，請任何人幫忙，我將不勝感激。 謝謝。

如何檢查處理器是否支持虛擬化技術。

您應該在/proc/cpuinfo文件的flags部分中查找以下兩個可能值之一： vmx (intel) 或svm (amd)。

您可以使用grep命令，而不是手動檢查此文件：

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

在您的 output 中，您可以找到vmx （Intel-VT 技術）：

flags       : ... vmx ...

這意味着您的 CPU 支持虛擬化技術。

修復更新 package 列表時出現的 404 錯誤。

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

上面的錯誤告訴您此存儲庫不適用於您當前的 Ubuntu 版本。
您可以在本文中找到詳細的解釋和可能的解決方法。 此外， 接受的答案也存在類似的問題。

簡而言之，您可以使用以下方法刪除此存儲庫：

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

然后更新 package 列表：

$ sudo apt update
