I would like to install kubectl version 1.2.4 on a machine. The Kubernetes documentation recommends using snap for installation on Ubuntu.

snap install --help is not very useful, the one promising parameter --revision= doesn't work:

$ sudo snap install --revision=1.2.4 kubectl
error: cannot decode request body into snap instruction: invalid snap revision: "\"1.2.4\""

I suspect that --revision expects a SHA rather than a semver.

The apt-get convention of using package=1.2.3 also doesn't work:

$ sudo snap install kubectl=1.2.4
error: snap "kubectl=1.2.4" not found

The usage documentation seems silent on the question.

Anybody know?

  1. you can run snap info kubectl which gives you a list of kubectl versions.
  2. Then you can install your preferred version with --channel like this sudo snap install kubectl --channel=1.6/stable --classic or if you want to upgrade / downgrade to specific version: sudo snap refresh kubectl --channel=1.6/stable --classic

It seems that version 1.2.4 Is not available in snap, in that case you can download the executable https://storage.googleapis.com/kubernetes-release/release/v1.2.4/bin/linux/amd64/kubectl

    why do we need --classic?

  • Same question as @lucidbrot - I often see the --classic flag but with no explanation as why that option would be used.

    --classic means the snap is not built with specific permissions (i.e. strict mode), so adding --classic means it will run like a traditional binary with most permissions.

  • How do we prevent the snap from being updated after installing a specific version?

    Preventing snap package upgrades: not impossible, but not elegant either (and for my team, this is a major shortcoming of snap): askubuntu.com/questions/1131182/…

  1. Run this 
    snap refresh --edge sublime-text
    to update sublime text to the version you want or 
    snap install --edge sublime-text
    to install sublime text.
  2. The --edge represent the channel
