inconsistent/absent chef packages in jammy

Hi,

There is no chef package in jammy. To install chef I've kept a focal sources.list file around.

$ apt-cache policy chef
chef:
  Installed: 15.8.25.3.gcf41df6a2-6
  Candidate: 15.8.25.3.gcf41df6a2-6
  Version table:
 *** 15.8.25.3.gcf41df6a2-6 500
        500 http://no.archive.ubuntu.com/ubuntu focal/universe amd64 Packages
        100 /var/lib/dpkg/status

But there is a ruby-chef-config package

$ apt-cache policy ruby-chef-config
ruby-chef-config:
  Installed: 15.8.25.3.gcf41df6a2-6
  Candidate: 16.12.3-2
  Version table:
     16.12.3-2 500
        500 http://no.archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
        500 http://no.archive.ubuntu.com/ubuntu jammy/universe i386 Packages
 *** 15.8.25.3.gcf41df6a2-6 500
        500 http://no.archive.ubuntu.com/ubuntu focal/universe amd64 Packages
        100 /var/lib/dpkg/status

But this gets a bit in the way because chef from focal is not compatible with the ruby-chef-config package from jammy. So in fact the ruby-chef-config package in jammy should be removed as long as there is no chef package. Also ohai

(Related but tangential: I had to downgrade some chef related package to the focal versions and put them on old to get the focal chef to work:

ohai hold
ruby-chef-config hold
ruby-chef-utils hold
ruby-net-sftp hold
ruby-uuidtools hold
)
