Failed to install KubeSphere via ks install kk on a fresh machine

[LinuxSuRen]

The command is:

ks install kk --kubernetesVersion v1.21.5

The error output is:

time="10:40:52 CST" level=error msg="Failed to connect to 192.168.0.3: Failed to validate ssh connection parameters: Failed to read keyfile \"/root/.ssh/id_rsa\": open /root/.ssh/id_rsa: no such file or directory" node=192.168.0.3
time="10:40:52 CST" level=warning msg="Task failed ..."
time="10:40:52 CST" level=warning msg="error: interrupted by error"
Error: Failed to init OS: interrupted by error
Failed to init OS: interrupted by error

It still cannot work after I generated the ssh key with the following command:

ssh-keygen

the error output is:

time="10:57:28 CST" level=error msg="Failed to connect to 192.168.0.3: could not establish connection to 192.168.0.3:22: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain" node=192.168.0.3

time="10:57:28 CST" level=warning msg="error: interrupted by error"
Error: Failed to init OS: interrupted by error

then, I put the content of /root/.ssh/id_rsa.pub into the end of /root/.ssh/authorized_keys. It works well.

Suggestion

I'd like to suggest doing all those work by the command ks install kk. So users don't need to do it over and over again.
