They said a new version would be ... and AWS Linux 2023 was released two years ago. I'd think there would be a lot of info and discussions on this but I cannot find a single reference to it. Maybe I misunderstood and there will just be a major release of AL2023 in 2025, but there is an end of support date for AL2023 so that seems confusing. Also I can't find any info on that major update if that is the case. ... As a former employee of Amazon Linux, there ... More on reddit.com

From the Amazon Linux 2023 documentation:

You can change the value of releasever using one of the following methods. These methods are listed in descending system priority. This means that method 1 overrides methods 2 and 3, and method 2 overrides method 3.

  1. The value in the command line flag, --releasever=latest, if it's used.
  2. The value that's specified in the override variable file, /etc/dnf/vars/releasever, if it's set.
  3. The currently installed version of the system-release package.

So releasever can be found with the one-liner: cat /etc/dnf/vars/releasever || rpm -q system-release

Original answer

Can be found like so: cat /var/log/dnf.log | grep -i "ddebug releasever:" | rev | cut -f 1 -d " " | rev | tail -n 1

To double check run dnf list system-release. The numbers should be identical. The packages amazon-linux-repo-s3 or kernel-livepatch-repo-s3 can be used in place of system-release.
