Self-hosted runners are broken about vswarm

So I might now what the reason is.
The control pane runs an groovy image which is ubuntu 20.10. There seems to be that there was a bug in the resource list.
I fixed this bug by updating the source.list

cat > /etc/apt/sources.list << EOF
deb http://old-releases.ubuntu.com/ubuntu/ groovy main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ groovy-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ groovy-security main restricted universe multiverse
# Optional
deb http://old-releases.ubuntu.com/ubuntu/ groovy-backports main restricted universe multiverse
EOF

However, then docker-compose binary fail and so on.
I think its not the right approach to fix it for ubuntu 20.10. We should define the version that is used for the control pane. Where can I do that?

[dhschall]

When I log into the runner container on the machine and follow the steps in the script already apt update fail

I think the problem is somewhere in the container config

[ustiugov]

the problem is in the apt repos configured. it's not about the container.

@shyamjesal @boramalper guys, could you please comment on that? I think that the docker image should be 20.04... I don't know why it's 20.10 at all

[shyamjesal]

Ubuntu 20.10 is deprecated. Changing the image to 20.04 should fix it. Source
I don't remember why it's 20.10 :-(

Can you please elaborate how if you know?

This is stock-knative runner. right?

[ustiugov]

Yes

[shyamjesal]

This is the flow:

1. "Download knative-kind installation script": step in setup-host.yaml copies a script located here as install-konk.
2. This script would be executed by create-runner.yaml.
3. When executed, install-konk calls install.sh script to create a kind container.
4. install.sh has kind image version hardcoded in K8S_VERSION variable. This currently is "v1.21.1@sha256:fae9a58f17f18f06aeac9772ca8b5ac680ebbed985e266f711d936e91d113bad".

Changing this version should work. The latest one in this series is v1.21.10.

@dhschall, I still experience a failure although I pulled the latest repo's version.

any suggestion?

[ustiugov]

ok, had to set up the remote host again.
