helm install isn't working behind proxy

Majed Dobyani <mbth201@...>

I use Ubuntu20.04, kubernetes 24 and helm 3. I already set up all proxy configurations for environment, apt , bashrc and wgerc and everything works fine. I can pull images from kubernetes and update the OS via proxy. But helm install is not working behind proxy and I got failed download. without proxy it is working fine.
I appreciate any help or clue to fix this issue and be able to install charts using proxy.
