The error you are seeing seems related to you not doing things as expected, see this old issue: https://github.com/rapid7/metasploit-framework/issues/7336

It specifically talks about your gpg key issue (missing key)

[edrapac]

Hi @nrathaus Could you explain a bit more when you say I am not doing things as expected? As far as I understand it, the steps I outlined to reproduce are the steps outlined by the official documentation to install metasploit-framework

[nrathaus]

Can you verify that this: /usr/share/keyrings/metasploit-framework.gpg

Exists?

This is where the key is stored - it seems this step failed

We can close this one - there is no response from @edrapac

Maybe a regression introduced by https://github.com/rapid7/metasploit-omnibus/pull/192
