Lens tries to download correct Kubectl version for the cluster and use that in Lens terminal. Some operating systems (namely Windows) might have restrictions set that prevent downloading and executing binaries from the default location that Lens is using. You can change the directory where Lens downloads the binaries in App Preferences. It’s also possible to change the Download mirror to use Azure if default Google is not reachable from your network. If downloading Kubectl is not option for you, you can define path to pre-installed Kubectl on your machine and Lens will use that binary instead.
