Failed to enable helm

When running microk8s.enable helm on edge channel I get the following output:

Enabling Helm

/snap/microk8s/1245/actions/enable.helm.sh: line 17: cd: /var/snap/microk8s/1245/tmp/helm: Permission denied

Hi, I’ve managed to reproduce this problem. It does seem to be caused by what @ktsakalozos said. I believe it affects all enable scripts that use the tmp foder.

I’m working on a VM, and I’ve added to /etc/sudoers:

Defaults    umask = 0027
Defaults    umask_override

Then, I’ve installed microk8s with sudo snap install microk8s --classic. Enabling any addon that creates the tmp folder will lead to this problem:

$ sudo microk8s enable istio
...
Istio is starting

To configure mutual TLS authentication consult the Istio documentation.
$ sudo usermod -a -G microk8s $USER
---- log out & log in ----
$ microk8s enable helm
Enabling Helm

/snap/microk8s/2948/scripts/wrappers/common/../../../actions/enable.helm.sh: line 17: cd: /var/snap/microk8s/2948/tmp/helm: Permission denied

I’ll try to create a PR with changes to the affected addons, wich are cilium, helm, helm3, istio and prometheus.
