Ubuntu 20.04环境下Kubernetes通过apt/snap安装失败的问题求助

大家好，我最近在Ubuntu 20.04上部署Kubernetes时碰到了一堆棘手的问题，想请教下社区里的大佬有没有解决思路或者能用的安装脚本？

先说说我的遭遇：
之前我一直用这条命令来安装Kubernetes的核心组件：

sudo apt install -y kubectl kubeadm kubelet

结果现在执行这条命令，直接返回一堆提示，说apt源里找不到这些包了，让我用snap安装：

No apt package "kubeadm", but there is a snap with that name.
Try "snap install kubeadm"

No apt package "kubectl", but there is a snap with that name.
Try "snap install kubectl"

No apt package "kubelet", but there is a snap with that name.
Try "snap install kubelet"

没办法，我只能按照提示用snap来安装：

sudo snap install kubectl --classic
sudo snap install kubeadm --classic
sudo snap install kubelet --classic

本以为这样就搞定了，结果执行kubeadm init的时候又出问题了，一堆警告不说，还提示kubelet服务没启用：

[init] Using Kubernetes version: v1.27.1
[preflight] Running pre-flight checks
W0517 14:44:01.250068 1034876 checks.go:1064] [preflight] WARNING: Couldn't create the interface used for talking to the container runtime: crictl is required by the container runtime: executable file not found in $PATH
[WARNING FileExisting-ethtool]: ethtool not found in system path
[WARNING FileExisting-socat]: socat not found in system path
[WARNING Service-Kubelet]: kubelet service is not enabled, please run 'systemctl enable kubelet.service'

我赶紧去执行启用kubelet的命令，结果更懵了：

Failed to enable unit: Unit file kubelet.service does not exist.

真的搞不懂Canonical这是操作了什么，好好的Kubernetes安装流程直接给搞崩了。有没有人有适配当前Ubuntu 20.04环境的可用安装脚本？麻烦分享一下，万分感谢！
