v1.20/stable : failing to install addons on utf <> ascii locale issue

Hi there,

Trying to install new 1.20 to implement the keda addon. But, it fails before. (the used procedure works fine with v1.19)

It seems to be related to a utf <> ascii locale issue

Snap install goes fine:

This runs on a GCE Ubuntu instance : ubuntu-2004-focal-v20201211 as per Google’s naming

When it goes to addons install:

microk8s enable dns | tee -a "$REPORT"
microk8s enable helm3 | tee -a "$REPORT"
microk8s enable rbac | tee -a "$REPORT"
microk8s enable dashboard | tee -a "$REPORT"
microk8s status --wait-ready

GCE’s Ubuntu says:

This system supports the C.UTF-8 locale which is recommended.
You might be able to resolve your issue by exporting the
following environment variables:

    export LC_ALL=C.UTF-8
    export LANG=C.UTF-8

Click discovered that you exported a UTF-8 locale
but the locale system could not pick up from it because
it does not exist.  The exported locale is "C.UTF-8" but it
is not supported

Let me know if additional Ubuntu config info is needed to understand the issue.

I see. 1.20 enable command has moved to using python. Previously on bash. Using python gave more features that are clunky and difficult to implement in bash. While what i mentioned above is purely my opinion, we can always check with @ktsakalozos and @knkski what they think. Reopening the issue for more discussion.
