STAGE 2B - Add Userdata - ISSUE

[Arwin]

Hello,

I encountered error while i just followed the demo it seems that the user-data is failing whenever i launch an instance from template.

Errno 2] No such file or directory: '/var/cache/dnf/amazonlinux-39b85c012216ab5c/packages/krb5-devel-1.21-3.amzn2023.0.4.x86_64.rpm'

when i tried to perform a -x only, it gets me this error regardless,
what i saw was this.

https://repost.aws/questions/QU_tj7NQl6ReKoG53zzEqYOw/amazon-linux-2023-issue-with-installing-packages-with-cloud-init

" I am attempting to install packages via cloud-init in an Amazon Linux 2023 instance. Sometimes it works, sometimes it fails with: "RPM: error: can't create transaction lock on /var/lib/rpm/.rpm.lock (Resource temporarily unavailable)" This issue occurs when attempting pkg installs in both a cloudconfig and a script. The most annoying part is that it fails most of the time but not always. And it doesn't always fail in the same place. Sometimes it get through cloudconfig pkgs and fails in the pkgs being installed by the script, sometimes it doesn't get that far.

""

but i didn't get far.

perform a sleep 120 so the cloud-init finish all it's setup before running the script,
