How to solve the problem with Helm?

Question

Openshift

Good afternoon.
After installing Helm (curl downloaded the tar.gz archive, unpacked it and copied it to /usr/local/bin/helm as described in https://www.ibm.com/support/knowledgecenter/en/SSB... ) here is the error:
[[email protected] ~]# helm version --tls

Additional Info:

[email protected] ~]# set | grep KUBE
KUBECONFIG=/install/os1/auth/kubeconfig
pem files are here where OpenShift is, but it doesn't look like they need to be copied to /root/.helm:

/install/os1/external-storage/snapshot /deploy/ca-certificates/etc/pki/ca-trust/extracted/pem/email-ca-bundle.pem
/install/os1/external-storage/snapshot/deploy/ca-certificates/etc/pki/ca-trust/extracted/pem/objsign-ca-bundle.pem
/install/os1/external-storage/snapshot/deploy/ca -certificates/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
