Can you confirm what version of puppet-agent is installed and being used?

3

puppet-agent.x86_64 7.17.0-1.el8.
this is weird, I have added https://yum.puppet.com/puppet7-release-el-7.noarch.rpm repo
why does it install el8?

4

That is strange, I tested the quickstart workflow myself and got the installer installed without issue. Perhaps try again fresh?

5

I will do that and update

same result…

can you think on a workaround/soluting?

So I have found a workaround.
I installed a puppet agent that is satisfied for el7, in my case puppet agent 7.16,
by doing so when I reinstalled foreman-installer the puppet agent dependency was already satisfied.
and the foreman-installer was installed successfully. YAY !!!

Saying that it is still weird when trying to install puppet agent using the puppet-release7
repo, puppet agent for el8 is installed.
I have probably messed up some configurations…
