Hello Team,

While trying to install the puppet agent on the SLES 12.5 I am facing difficulty of unknown key as mentioned in the subject.

Due to this issue my auto-installer on AWS image builder is also rejecting the package. To follow the strict compliance I don't want to install anything unverified in my environment.

Can you please by adding a correct key to the packages or let me know how we can add a correct key to the package.

Please see below warning messages for more info:

This is likely due to the changes described in this post https://groups.google.com/g/puppet-dev/c/mPsyy1A5YUU/m/dWqUMP3SBQAJ

Since the PC1 repos are EOL, please use these instead:

https://yum.puppet.com/puppet7-release-sles-12.noarch.rpm
https://yum.puppet.com/puppet8-release-sles-12.noarch.rpm
