Actual Behavior
When starting v1.0.0-beta, get the following error:
There was an unknown error starting Kubernetes: FetchError: request to https://update.k3s.io/v1-release/channels failed, reason: certificate signature failure
This only appears to occur when connecting from inside the corporate network, which uses a self-signed cert for the internal proxy. When disconnected from the internal network, everything starts up as expected.
Steps to Reproduce
- Start
1.0.0-beta.1for the first time after installation, while behind a firewall with a self-signed cert. - Receive the error shown above (and in the screenshot, below) prior to downloading Kubernetes.
Result

Expected Behavior
Kubernetes should start.

Ya - that’s where I found what I posted. There was nothing in there specifically from the installation, and what I posted was from the first startup after I installed, which is when it tried to pull everything down.
