Discussion:
kippo is an SSH honeypot service, here is the module definition: And of course, it needs the kippo package : But now the module is broken because the was removed : ( Here is the commit: and corresponding PR: Should we remove the broken module or re-pachaging the ...? Steps to reproduce the behavior: line to error log says is not exists. I'm not found any maintainers from the module, the deleted package's maintainer is Maintainer information:
I am no longer a regular user of kippo so i didn't mind if the module is deprecated along with the package.
Maybe I can make a PR to remove the module, sorry for bothering you.
