Error saying No apt package kubeadm but there is a snap with that name Try snap install kubeadm

Question

I am trying to install kubernetes on Ubuntu 18.04. I executed the following command:

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
echo 'deb http://apt.kubernetes.io/ kubernetes-xenial main' | tee /etc/apt/sources.list.d/kubernetes.list
apt-get install kubelet kubeadm kubectl -y

I get the following error:

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

Answer 1

You're getting this error because you do not have the required repository for installing kubernetes. Executing these two commands should ideally add repositories to your stack but I dont think thats worked out very well.

sudo nano /etc/apt/sources.list

add the repo here

sudo nano /etc/apt/sources.list.d/kubernetes.list

It can be related with timezone too as you can see here : https://askubuntu.com/questions/1061675/apt-package-update-is-failing-for-ubuntu-18-04-lts/1061678#1061678

No.

Actually you need to add:

"sudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"

Answer 2

After adding gpg key and repositories, you must do apt-get update to load the repositories. Once they are loaded, the packages will be found.
