A clear and concise description of what happend.

Hello,

I'm trying to build from scratch Kubesphere on K3s based Raspberry pi ARM64 . For this reason I already made some small adjusments to downlaod right K3s bin file and also I have replatformed ks-installer to support arm64. Everything went smoothly untill this error

TASK [preinstall : KubeSphere | Stopping if Kubernetes version is nonsupport] ***
fatal: [localhost]: FAILED! => {"msg": "The conditional check 'kubernetes_version.stdout is version('v1.15.0', '>=')' failed. The error was: Version comparison: 'LooseVersion' object has no attribute 'version'"}

Relevant log output

@pixiake Please take a look on this issue.

[pixiake]

https://github.com/kubesphere/ks-installer/blob/453c47bdba3f9d91c3588aefd86ec6fe4fba874c/roles/preinstall/tasks/precheck.yaml#L11

It seems a version check error in ks-installer. You can check the cluster version using the following command:

kubectl version -o json | jq -r '.serverVersion.gitVersion'

or, You can also try to restart ks-installer:

kubectl rollout restart deploy -n kubesphere-system ks-installer

[gaugys]

hey,

I have a feeling that KS Installer is not able to handle +k3s1 suffix: they output is here:

  "clientVersion": {
    "major": "1",
    "minor": "21",
    "gitVersion": "v1.21.4+k3s1",

    "gitTreeState": "clean",
    "buildDate": "2021-08-19T19:10:03Z",
    "goVersion": "go1.16.6",
    "compiler": "gc",
    "platform": "linux/arm64"
  },
  "serverVersion": {

    "goVersion": "go1.16.6",
    "compiler": "gc",
    "platform": "linux/arm64"
  }
}

the restart didn't help. and still the same error:

I have submitted an issue to ks-installer.

You can try to delete the task of version checking, and then rebuild the image according to ks-installer's Dockerfile.
