Parsing the latest version is failing

[abelfodil]

Summary

Ensure the release version is set as a fact step is failing due to error {"msg": "'dict object' has no attribute 'json'"}.

Upon inspection of https://update.k3s.io/v1-release/channels, it seems the json format is not respected anymore when headers are supplied.

e.g. running curl --header "Accept: application/json" https://update.k3s.io/v1-release/channels yields an HTML page with JS code.

Issue Type

• Bug Report

Steps to Reproduce

Set k3s_release_version: v1.29 which will trigger the pre-checks and run into the issue.

Expected Result

The precheck step should pass.

Actual Result

The precheck step fails.

Fix

A possible fix is to not check the version at all and instead use the following links:

• When version is of format: v{MAJOR}.{MINOR} simply use https://update.k3s.io/v1-release/channels/{{k3s_release_version}} link which will lead to the latest version of that release family.
• When version is not specified and channel is stable, use https://update.k3s.io/v1-release/channels/stable
• When version is not specified and channel is latest, use https://update.k3s.io/v1-release/channels/latest
