Answer 1

This package contains in deb http://ftp.de.debian.org/debian buster main repo which is not available in ubuntu.

First you need to do add this to /etc/apt/sources.list like below

#for kubectlx
deb [trusted=yes] http://ftp.de.debian.org/debian buster main

Then run

sudo apt-get update

Then you can install using this cmd.

sudo apt install kubectx

Answer 2

The following steps worked for me;

1. sudo apt-get update
2. sudo git clone https://github.com/ahmetb/kubectx /usr/local/kubectx
3. sudo ln -s /usr/local/kubectx/kubectx /usr/local/bin/kubectx
4. sudo ln -s /usr/local/kubectx/kubens /usr/local/bin/kubens
5. Enter kubens in your console and you should be able to see your namespaces

Answer 3

There is a kubectx snap package in all currently supported versions of Ubuntu:

sudo snap install kubectx

Answer 4

I successfully installed ctx and ns as kubectl plugin using Krew.

kubectl krew install ctx
kubectl krew install ns

There's one minor catch. You won't use the commands like this:

kubectx
kubens

But rather like this:

kubectl ctx
kubectl ns
