Instalation on Amazton Linux 2 not working

[udondan]

The installation instructions do not mention AL explicitly so I'm not sure this is meant to work or is intentionally not supported. But since it's CentOS based I think it should work / should not be too complex to make work.

Following the installation instructions for CentOS, you will get this 404 error on Amazon Linux 2

$ sudo yum -y update

Or maybe it's a general problem as described in aquasecurity/trivy#471?

So the problem is the release version. If you replace $releasever (2 on AL2) with a 7 (what AL2 is based on) the repo perfectly works. Maybe it should just be added to the docs.

@udondan
Can we use the same trick for Amazon Linux 2022?
From what I could find Amazon Linux 2022 is based off Fedora and not RedHat.
