k3s installation script failing

[daemon1024]

Environmental Info:
K3s Version: latest/stable

Node(s) CPU architecture, OS, and Version:
*

Cluster Configuration:
*

Describe the bug:
We cannot use the convenience script to install k3s

Steps To Reproduce:

❯ curl -sfL https://get.k3s.io | sh -
[INFO]  Finding release for channel stable
[INFO]  Using stable as release
[INFO]  Downloading hash https://github.com/k3s-io/k3s/releases/download/stable/sha256sum-amd64.txt
[ERROR]  Download failed

Expected behavior:
Installation Success

Actual behavior:
Installation Failure due to failure to download

Additional context / logs:
Tried removing sha verification still fails to download binary. Seems like Github has deprecated certain URLs.

The host is down for this website,

Hi !
There seems to be something wrong with your DNS server setup. In my case, it is normal

[brandond]

Our backend channel servers appear to be experiencing intermittent issues. I've reached out to our infrastructure team.

[daemon1024]

Hey Folks, It seems to be working as expected now.

@brandond thanks for forwarding the issue.

@Miaoxiang-philips the issue was happening across machine and even in our Github CI runners 😅 Our runners are now running as expected tho.

Yeah also seeing issues downloading the SHA256 release file as well with Kube-Hetzner :(

module.kube-hetzner.null_resource.first_control_plane (remote-exec): [INFO]  Using latest as release
module.kube-hetzner.null_resource.first_control_plane (remote-exec): [INFO]  Downloading hash https://github.com/k3s-io/k3s/releases/download/latest/sha256sum-amd64.txt

We could probably enhance the install script to be a little more resilient to channel server outages.

Just to share a little bit about what this looks like on our side - this seems to be triggered by an anomalous use pattern several orders of magnitude above normal:

sudden influx from a usual 50k a min to a spike over 8mil a min and it stayed around 1-1.5 mil for several hours

Currently seeing this as well. It sounds like this is something expected to clear up soon? Or is this something you need help/logs to debug? Happy to provide assistance if I can.

As soon as I post this, I'm able to reach it again.

I am also facing this issue.

i have done this by passing the version : curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.29.6+k3s2 K3S_KUBECONFIG_MODE=777 sh -

I am also experiencing this issue.

i have done this by passing the version : curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.30.3+k3s1 K3S_KUBECONFIG_MODE=777 sh -

However, I was able to work around it thanks to @Aias00's suggestion.

I am experiencing the same issue on v1.29.3+k3s1 install k3s script

sudo bash k3s_install.sh --write-kubeconfig-mode "0644" --docker"

@alexlianides — I updated my comment. I previously copied the text from @Aias00's comment but after seeing yours realized that was not exactly what is working for me.

This is working for me right now:

curl -sfL https://get.k3s.io/ | INSTALL_K3S_VERSION=v1.30.3+k3s1 K3S_KUBECONFIG_MODE=777 sh -

@mikeschinkel while this fix does work, this fix introduces security issues due to the open permissions it sets to the k3s cluster. Thank you for the tip though.

@brandond is the current issue still due to a server availability issue? or is this a new error?

[brandond]

It's the same thing. When it's resolved we'll close and unpin the issue. I don't have any additional information to provide.

Note that only the INSTALL_K3S_VERSION argument is necessary to work around the channel server outage. You can reference the docs for more information on passing args to the install script: https://docs.k3s.io/reference/env-variables

I'm going to lock this issue to prevent additional off-topic discussion but leave it open; if there are updates I will provide them here.
