kubectl install : error: snap "kubectl" requires classic confinement which is only available on classic systems

[Jayashree]

Hi,

I am trying to install kubernetes using the command: "sudo snap install kubectl --classic"

But I am getting error and not able to install "snap "kubectl" requires classic confinement which is only available on classic systems"

Can you please help in resolving this.

snap version:
----------------
admin@localhost:~$ snap version
snap 2.41
snapd 2.41
series 16
kernel 4.4.0-164-generic

admin@localhost:~$ sudo snap install kubectl --classic
error: snap "kubectl" requires classic confinement which is only available on classic systems
admin@localhost:~$ sudo snap install kubectl

Ubuntu Core only supports strictly confined snaps, so it's not suitable to install kubectl or other classic snaps. See https://snapcraft.io/docs/snap-confinement for more information.

Ok if I want to install kubectl or other classic snaps, what I need to do??
Any solution?
