我正在升级 Ubuntu 18.04 系统。命令sudo do-release-upgrade
失败并显示以下错误。此系统是 k8s 主控,但我这样做了sudo apt purge kubeadm kubectl kubelet
。为什么它仍在寻求升级 k8s?

答案1
“为什么还想升级k8s呢?“
记住 apt 的工作原理:包来自人类指定的来源。
您删除了 k8s 软件包,但保留了 k8s 源。
因此,系统自然会寻找该来源。如果没有找到,就会向人类抛出错误。
您可以通过从 /etc/apt/sources.list.d/ 中的 apt 源中删除源来解决问题。或者,您也可以从“软件和更新”控制面板 -> 其他软件 -> 删除该源中删除源。
