Non usual Apt problems (Kaisen installed over existing SO)

Hi,

Thanks for the help, and for the warns.

I found this info about the package pinning priority:

**100 < P <=500**
causes a version to be installed unless there is a version available belonging to some other distribution, or the installed version is more recent.

**0 < P <=100**
causes a version to be installed only if there is no installed version of the package.

From: Understanding apt-pinning in Linux – Sweetcode.io

I’m trying to adjust the priorities and appears to be working:

$ sudo apt policy libreadline7
libreadline7:
  Instalado: (nenhum)
  Candidato: 7.0-3
  Tabela de versão:
     7.0-3 90
         90 https://mirror.ufscar.br/ubuntu bionic/main amd64 Packages

In that moment(still adjusting), the priority is:
Kaisen: 500, Debian Sid: 100, Debian unstable: 100, Ubuntu Bionic: 90…

I will be adjust a little bit more, to solve other packages problem and make available in a gist.

Thanks for the help. I will back with the results!
