Did you test the change, I expect it won't work and result in the same error as metioned in #2102 See also PR actions/runner#1585

We have been running Ubuntu 22.04 LTS on our runners for about a month now successfully. I can share our config if you'd like.

[npalm]

Please share your config, since running ./bin/installdependencies.sh is failing for me.

We don't have anything proprietary in this config, so I'll share with you.

Then for our userdata, we actually took the example and instead of using a rootless runner, we install it at the system level since our VMs are ephemeral.

Can you share the userdata template as well?

This is the userdata file that is getting passed in (I removed some commented out lines for conciseness):

Hmzz, user_data is not relevant. You are installing all your depencies in a pre-build AMI most likely. Do you run the github runner install dependency script?

[dylanmtaylor]

Hmzz, user_data is not relevant. You are installing all your depencies in a pre-build AMI most likely. Do you run the github runner install dependency script?

We don't use pre-build AMIs, just grab the latest with the filter name = ["ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-amd64-server-*"]. We grab that at run time and add the packages then. I think the macros

${install_runner}
and ${post_install}

which are interpolated by the module do the dependencies.

Let me see if I can grab the userdata off the instance and see what it actually ends up being.

This is from one of the instances running right now. I'm going to redact our S3 bucket info, etc. but I'll leave some old commented lines in. It's running the public AMI, 099720109477/ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-amd64-server-20220604 and it's working.

Since the start script is exiting at a failure installation continues and the runner even got started. So not sure about the impact on the runner.

Maybe ours has this error as well. Surprisingly though, the runner has been working absolutely fine.
