concourse start up problem

[vasgupta]

Hello, I can't start the concourse web server container. I get this error below, it has something to do with the iptables library. The code for the iptables startup should be iptables-**legacy** -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT , but I don't know how to download the older versions of concourse in the container or enter this code in the source code for this container.

It's a WSL2 problem related here microsoft/WSL#7948 (comment)

Oh hey I just figured it out. Just use version 7.7.1 instead of the version it downloads automatically. To do that, all you gotta do is change the yaml file you download in the first step to include version 7.7.1 . This is what it should look like now. image: concourse/concourse:7.7.1

hope this helps someone who is stuck on it as well.
